Abstract
OBJECTIVE The aim of this study was to determine the intraoperative corrective effect of the aponeurotic release of semimembranosus (SM) as a single procedure or an adjunct procedure to distal myotendinous release of semitendinosus (ST) and myofascial release of SM lengthening in the correction of knee flexion deformity in cerebral palsy (CP). METHODS In this prospective study, 46 knees of 23 consecutive ambulatory patients (15 boys and 8 girls; mean age=8.33 years; age range=5-12 years) with spastic diplegic CP with a gross motor function classification system level (GMFCS) II or III were included. The patients were then divided into 2 groups. In group I, there were 10 patients (4 boys, 6 girls; mean age=8.6±2), and combined release of ST in the myotendinous junction and SM in the myofascial junction, followed by aponeurotic release of SM were carried out. In group II, there were 13 patients (2 girls, 11 boys; mean age=8±2.35), and aponeurotic release of SM was done first and followed by the combined release of ST in the distal myotendinous junction and the myofascial release of SM. Intraoperative popliteal angle (PA) measurements were recorded in each group. RESULTS PA was reduced from 58.1°±7.6° (range=46°-75°) to 41.2°±8.8° (range=20°-54°) in group 1 and from 59.1°±11.3° (range=40°-87°) to 42.7°±10.8° (range=24°-64°) in group 2. No significant difference was observed between the groups in terms of reduction in PA (p=0.867). In group 1, adding the aponeurotic release of SM further reduced the PA to 31.7°± 8.5° (range=14°-47°) (p=0.002). In group 2, adding the myotendinous release of ST and myofascial release of SM further reduced the PA to 32.9°±7.2° (range=16°-44°) (p=0.004). There was no significant difference between the final PA values in the 2 groups (p=0.662). There was no difference in terms of early complications. CONCLUSION Aponeurotic release of SM is equally effective to reduce the intraoperative PA with combined myotendinous release of ST and myofascial release of SM. Combining all the 3 procedures provides a better correction without forceful manipulation or lengthening of the lateral hamstrings during the correction of knee flexion deformity in CP.

Abstract
To evaluate the clinical outcomes of an anterolateral approach for lateral humeral condylar fractures in children. The patients aged < 15 years undergoing surgery with an anterolateral approach for humeral lateral condylar fractures between April 2005 and March 2014 were investigated. Medical records and radiographs from 15 patients were reviewed. Average patient age at surgery was 6.0 years (range, 3-10 years). Based on Jakob's classification, 12 patients had type II fractures, and 3 patients had type III fractures. Based on Milch classification, 1 elbow was type I, and 14 elbows were type II. The average postoperative follow-up duration was 16.4 months (range, 6-58 months). Postoperative complications, and radiographic and clinical findings, including range of motion and Flynn criteria were evaluated. To evaluate humeral deformity, Baumann angle (BA) and the carrying angle (CA) were calculated on anteroposterior radiographs. There were no postoperative complications, including secondary displacement, deep infection, nonunion, avascular necrosis, or cubitus varus or valgus deformity. In the injured elbow, follow-up radiographs revealed an average BA of 69.1° (range, 57-84°), versus 70.9° (range, 61-83°) on the contralateral side. The average CA on the injured side was 10.3° (range, 4-20°) versus 12.3° (range, 6-24°) on the contralateral side. BA gain and CA loss (affected- compared with contralateral sides) averaged -1.4° (range, -17° to 9°) and 2.3° (range, -2° to 6°), respectively. The mean range of motion in the affected elbow averaged 4.7° (range, 0-15°) in extension and 139.7° (range, 135-140°) in flexion. Over 5° loss of range of motion in the affected elbow compared with the contralateral side was not observed. However, 2 patients experienced over 5° loss of CA in the affected elbow versus the contralateral side. Based on Flynn criteria, clinical results for both cosmetics and function were excellent in 13 patients, and good in 2. The advantages of the anterolateral approach are combining an optimal view of the anterior articular surface of the trochlea and capitellum and a limited risk of devascularization injury. We strongly recommend an anterolateral approach for these fractures in children to prevent postoperative deformity and to achieve anatomical reduction and reliable fixation.

Abstract
OBJECTIVE To quantify the bone density and stress distribution patterns in long-standing cubitus varus and clarify the effects of the deformity on bone density. DESIGN We created three-dimensional computed tomography (CT) elbow models from 21 patients with long-standing cubitus varus deformities without advanced osteoarthritis (OA) and assessed the deformity by superimposing the affected humerus onto a mirror-image of the contralateral normal. Elbows were divided into 13 regions before measuring the bone density of each region and comparing the percentage of high-density volume (%HDV) between affected and normal sides. We constructed finite element models and quantitatively analyzed stress distribution. RESULTS Average degrees of deformities were 20.1° of varus, 6.4° of extension, and 12.7° of internal rotation. The medial side of the affected humerus and ulna, Anteromedial trochlea (P < 0.001), Medial coronoid (P = 0.004), and Medial olecranon (P = 0.049) had significantly higher %HDVs than their normal counterparts. Conversely, %HDVs on the affected lateral side, Capitellum (P < 0.001), Anterolateral trochlea (P = 0.010), Posterolateral trochlea (P < 0.001), Lateral coronoid (P = 0.007), and Lateral olecranon (P < 0.001) were significantly lower than the normal side. The affected radial head %HDVs at Anterolateral and Posteromedial quadrants were high (P = 0.007) and low (P = 0.007), respectively. The bone density distribution coincided with stress distribution patterns revealed by finite element analysis (FEA), except in the lateral region influenced by forearm rotation. CONCLUSIONS Repetitive stress on the medial elbow may alter bone density distribution patterns, probably presenting from early stage of OA.

Abstract
Background acquired joint contractures have significant effects on quality of life and functioning. Objective to determine the effects of interventions to prevent and treat disabilities in older people with acquired joint contractures. Methods systematic search (last 8/2016) via Cochrane Library, PubMed, EMBASE, PEDro, CINAHL, trial registries, reference lists of retrieved articles and scientific congress pamphlets. Controlled and randomised controlled trials in English or German comparing an intervention with another intervention or standard care were included. Two independent researchers performed the selection of publications, data extraction and critical appraisal. Results seventeen studies with 992 participants met the inclusion criteria: 16 randomised controlled trials and 1 controlled trial (nursing homes = 4, community settings = 13). The methodological quality of the studies varied. Splints were examined in four studies, stretching exercises in nine studies, and ultrasound, passive movement therapy, bed-positioning and group exercise were each examined in one study. Studies on splints revealed inconclusive results regarding joint mobility or spasticity. Five of seven studies that assessed active stretching programmes for healthy older people reported statistically significant effects on joint mobility in favour of the intervention. Pain, quality of life, activity limitations and participation restrictions were rarely assessed. Conclusion the evidence for the effectiveness of interventions to prevent and treat disability due to joint contractures is weak, particularly for established nursing interventions such as positioning and passive movement. Better understanding is required regarding the delivery of interventions, such as their intensity and duration. In addition to functional issues, activities and social participation should also be studied as outcomes.

Abstract
Objectives It is known that the screws of the eight-plate hemiepiphysiodesis construct diverge as growth occurs through the physis. Our objective was to investigate whether there is a correlation between the amount of change of the joint orientation angle (JOA) and that of the interscrew angle (ISA) of the eight-plate hemiepiphysiodesis construct before and after correction. Patients and methods After the institutional review board approval, medical charts and X-rays of all patients operated for either genu valgum or genu varum with eight-plate hemiepiphysiodesis were analyzed retrospectively. All consecutive patients at various ages with miscellaneous diagnoses were included. JOA and ISA were measured before and after correction. After review of the X-rays, statistical analyses were performed which included Pearson correlation coefficient and regression analyses. Results There were 53 segments of 30 patients included in the study. Eighteen were males, and 12 were females. Mean age at surgery was 9.1 (range 3–17). Mean follow-up time was 21.5 (range, 7–46) months. The diagnoses were diverse. A strong correlation was found between the delta JOA (d-JOA) and delta ISA (d-ISA) of the eight-plate hemiepiphysiodesis construct (r = 0.759 (0.615–0.854, 95%CI), p < 0.001). This correlation was independent of the age and gender of the patient. Conclusions There is a strong correlation between the d-ISA and the d-JOA. The d-ISA follows the d-JOA at a predictable amount through formulas which regression analysis yielded. This study confirms the clinical observation of the diverging angle between the screws is in correlation with the correction of the JOA. Level of evidence Level IV, Therapeutic study.

Abstract
Objective The present study assessed functional and radiographic outcomes of distraction osteogenesis treatment of post-traumatic elbow deformities in children. Methods Eight children were treated between 2008 and 2013 for post-traumatic elbow deformities using distraction osteogenesis. Mean age at time of operation was 10.9 years. Six patients had varus and 2 had valgus deformity. Magnitude of correction, fixator index, complications, carrying angle, and elbow range of motion were assessed. Functional results were graded according to protocol of Bellemore et al. Results Mean follow-up was 43 months. Mean preoperative varus deformity in 6 patients was 29.2° and valgus deformity in 2 patients was 28.5°. Preoperative flexion and extension of elbow were 123.8° and −10.6°, respectively. Mean carrying angle was 9° valgus at last follow-up. Mean flexion and extension were 134.4° and −6.0°, respectively. Change in carrying angle was statistically significant (p = 0.002). There were 2 grade 1 pin tract infections and 1 diaphyseal fracture of humerus. Functional outcome was rated excellent in 7 patients and good in 1 patient. Conclusion Ilizarov distraction osteogenesis is a valuable alternative in treatment of elbow deformities in children. The surgical technique is simple and correction is adjustable. Gradual correction prevents possible neurovascular complications and minimally invasive surgery produces less scarring. Compliance of patient and family is key factor in the success of the outcome.

Abstract
Objectives The purpose of this study was to compare the outcomes of non-operative treatment and operative repair of grade III injuries with complete rupture of the collateral ligament of the proximal interphalangeal (PIP) joint. Patients and methods Seventeen patients with grade III injuries with at least 6 months of follow-up were included. Seven patients underwent non-operative treatment and 10 patients underwent operative treatment. We evaluated the following clinical outcomes after treatment: 1) range of motion of the PIP and distal interphalangeal (DIP) joints, 2) joint stability, 3) pain score, and 4) amount of fusiform deformity of the PIP joint. Results There was no instability in the lateral stress test in either group. The ranges of motion of the PIP and DIP joints were not statistically different between the two groups at final follow-up. However, the ranges of motion recovered more quickly in the operative group than the non-operative group within the first 3 months after treatment. Patients in the operative group had less pain and better cosmetic appearance of the PIP joint. Conclusion Our results suggest that operative repair of the PIP collateral ligament can provide good joint stability, rapid functional recovery, and minimize fusiform deformity of the PIP joint.

Abstract
Patients with severe varus deformity of the knee (≥15° varus) usually are not considered good candidates for minimally invasive total knee arthroplasty (TKA). The goal of this study was to retrospectively investigate outcomes in patients with severe varus deformity after minimally invasive TKA. A study group of 52 patients with a tibiofemoral mechanical axis of 195° or greater was compared with a matched control group of 55 patients with a tibiofemoral mechanical axis of less than 195°. Clinical and radiographic evaluations according to the American Knee Society rating system were obtained preoperatively and postoperatively, and postoperative patient satisfaction in the 2 groups was compared. All patients were followed at a mean of 3 years (range, 2-5 years). Preoperatively, clinical knee and function scores and range of motion were inferior in the study group compared with the control group (P<.001). However, at the latest follow-up, both groups of patients were satisfied with the clinical results, and no significant differences were found in the knee and function scores (P>.05). Radiographic evaluation showed no differences in the mechanical axis, femoral component valgus angle, and tibial component valgus angle, and all outliers of the radiographic parameters between the 2 groups postoperatively (P >.05). The study results showed that mini-midvastus TKA did not result in more inaccurate implant positioning in patients with severe varus deformity of the knee. The clinical outcome in the group with severe varus was comparable to that in the group with less severe varus

Abstract
BACKGROUND Pre-school age is a period of intensive development when children shape their posture, habits and motor memory. In recent years an increased incidence of postural problems has been observed among children and adolescents. This process results from civilisation progress and sedentary life style. Most of the early-detected abnormalities are of a functional nature and are relatively easy to correct. However, if no preventive measures are taken, deformities of bones and joints may develop which are difficult to treat and result in serious health disorders. The aim of our study was to evaluate physical fitness in children of pre-school age depending on diagnosed postural problems. MATERIALS AND METHODS The study included 64 children aged 6-7 years, in which abnormalities of body posture were diagnosed using the Wolański method. The children were classified into two groups. Group 1 comprised children with abnormalities in the chest and shoulder girdle, and group 2 comprised children with lower limb abnormalities. Physical fitness was evaluated using the Modified Wrocław Test for Physical Fitness by B. Sekita (1988). RESULTS We found a statistically significant difference (p = 0.0148) between groups in a 20 m run. Test results demonstrated that dysfunctions of lower limbs influenced the times for longer distance runs, but no statistically significant difference was found between the groups for shuttle run times. Children from group 2 had lower long jump scores compared to group 1, but the difference was not statistically significant. A statistically significant difference (p = 0.0375) was found for medicine ball throw scores. Children from group 1 had higher scores. This can be explained by the higher number of boys in that group, who have greater physical strength than girls. RESULTS Abnormalities of lower limbs in the studied group of children had a statistically significant influence on reduced physical fitness measured with the Sekita test. Abnormalities of the shoulder girdle and chest in the studied group of children had no effect on reduced physical fitness measured with the Sekita test.

Abstract
INTRODUCTION In high tibial osteotomies (HTO) the correction needs to be precise and intra-operative assessment is essential. The purpose of this study was to evaluate the use of the intra-operative clinical mechanical axis measurement and compare it to the post-operative weight bearing situation on standing whole leg radiographs (WLR). Secondly, we evaluated the preoperative planned wedge size and compared it to the final results in 27 HTOs. METHODS The mechanical axis deviation (MAD), expressed as a percentage of the tibial width (0% is medial edge, 100% is lateral edge) and the hip-knee-ankle angle (HKA) were calculated and analyzed. Preoperative planning was done by projecting the desired mechanical axis on the lateral tibial spine on the WLR and subsequently calculating the necessary correction angle. A 3° valgus correction was desired. RESULTS The results showed a preoperative standing MAD of 26.6%, or about halfway the medial tibial plateau. The MAD was corrected to 57.0% intra-operative, meaning a slight valgus. On the postoperative standing WLR, the MAD had shifted significantly to 62.0% (95% CI=-9.2 to -2.7; p<0.01) compared to the intra-operative 57.0% axis. The HKA angle changed 8.2° from 5.1° varus preoperative to 3.1° valgus postoperative. CONCLUSION When aiming the mechanical axis at the lateral tibial spine, a slight undercorrection was introduced, but due to a valgus shift while weight bearing, a satisfying final outcome of 3° valgus average was achieved. Preoperative calculation of the wedge size remains important for surgical planning, but it does not always correspond to the actual used wedge size.

Abstract
OBJECTIVE To investigate the surgical technique and the clinical results of total knee arthroplasty (TKA) in treating end-stage gonarthrosis combined with valgus knee deformity. METHODS Between November 1998 and October 2010, 64 patients (72 knees) with end-stage gonarthrosis combined with valgus knee deformity underwent TKA by a medial parapatellar approach. Of the 64 patients, 18 were male and 46 were female with an average age of 62.5 years (range, 23-82 years), including 44 cases (49 knees) of osteoarthritis, 17 cases (20 knees) of rheumatoid arthritis, 2 cases (2 knees) of haemophilic arthritis, and 1 case (1 knee) of post-traumatic arthritis. Bilateral knees were involved in 8 cases, and single knee in 56 cases. The flexion and extension range of motion (ROM) of the knee joint was (82.2 +/- 28.7) degrees; the femur-tibia angle (FTA) was (18.0 +/- 5.8) degrees; according to Knee Society Score (KSS) criterion, the preoperative clinical score was 31.2 +/- 10.1 and functional score was 37.3 +/- 9.0. According to Krackow's classification, there were 65 knees of type I and 7 knees of type II. By medial parapatellar approach, conventional osteotomy and Ranawat soft tissue release were performed in all cases. Prosthesis of preserved posterior cruciate ligament were used in 7 cases (7 knees), posterior stabilize prosthesis in 54 cases (60 knees), constrained prosthesis in 4 cases (5 knees). RESULTS Incisions healed by first intention in all cases. Peroneal nerve palsy occurred in 1 patient with haemophilic arthritis, severe valgus deformity (FTA was 41 degrees), and flexion contracture (20 degrees), which was cured after 1 year of conservative treatment. Revison surgery was performed in 1 case of deep infection at 2 years after surgery. All the patients were followed up 4.9 years on average (range, 1-13 years). At last follow-up, the FTA was (7.0 +/- 2.5) degrees, showing significant difference when compared with preoperative value (t = 15.502, P = 0.000). The KSS clinical score was 83.0 +/- 6.6 and functional score was 85.1 +/- 10.5, the flexion and extension ROM of the knee joint was (106.1 +/- 17.0) degrees, all showing significant differences when compared with preoperative values (P < 0.05). Five patients had 12-15 degrees valgus knee deformity, but the function of the affect knees were good. CONCLUSION TKA is an effective way for the patients with end-stage gonarthrosis combined with valgus knee deformity by medial parapatellar approach combined with conventional osteotomy and Ranawat soft tissue release. The correction of deformity and improvement of joint function can be achieved significantly. The clinical result is satisfactory.

Abstract
The purposes of this study were to describe the changes in tibial torsion and knee rotation in varus osteoarthritic knees and to check the reliability of reference axis, for tibial component placement, based on femoral transepicondylar axis in these patients. A secondary goal was to determine which reference axis based on proximal tibia is most accurate for determining tibial component rotation. Fifty-two varus osteoarthritic knees and 20 normal knees were analyzed using computed tomographic scan. Tibial torsion and knee rotation were significantly reduced in patients with osteoarthritis. Reference axis based on posterior tibial condyles was most accurate and least variable for tibial component alignment. A significant negative correlation was found between knee rotation and tibial axis based on transepicondylar axis (r = -0.485).

Abstract
We prospectively assessed the results of 239 primary total hip replacements performed using a conical stem combined with modular necks of different lengths and inclinations (Modulus System, Lima Corporate San Daniele Del Friuli, Udine, Italia) in 222 patients (50 men, 172 women), undergoing surgery between October 2001 and December 2006 and presenting with anatomical deformities of the proximal femur and/or acetabulum, including developmental dysplasia (DDH), ankylosis, and sequelae of osteotomies or fractures. Such conditions can make hip replacement problematic. The mean age at the time of surgery was 57.6 years (22 ÷ 83). No patients were lost to follow-up. 3 femoral components underwent revision. At a mean of 5 years follow-up the Harris Hip Score showed a significant improvement, increasing from 35 preoperatively to a mean of 96.6. Using Kaplan-Meier analysis the survival rate at 5 years was 98.28%. The Modulus stem showed good mid-term results in terms of survival, as well as clinical and radiographic outcome.

Abstract
PURPOSE To clarify the correlation between a scaphoid deformity and carpal malalignment in patients with scaphoid waist nonunion and to investigate how accurately a corrective bone graft improves carpal malalignment according to the preoperative plan. METHODS A total of 38 patients were analyzed retrospectively. Surgery was performed according to the anterior wedge bone graft method described by Fernandez. The scaphoid deformity and carpal malalignment were evaluated by the changes in the intrascaphoid angle (ISA) and axial length (AL) and by the changes in the radiolunate angle (RLA) and scapholunate angle (SLA), respectively, compared with the uninjured side by using standardized x-rays. Each variable was measured at 1 year after surgery. By performing multiple regression analysis, the correlation between the scaphoid deformity and carpal malalignment and between the correction of the scaphoid deformity and the change in carpal alignment were analyzed. RESULTS Compared with the uninjured side, the mean respective changes in the ISA, AL, RLA, and SLA were 11°, -1.3 mm, 14°, and 11°, preoperatively. The changes in the RLA and SLA correlated with the change in the ISA, but not with the change in the AL. The mean postoperative corrections of the ISA and AL were 15° from full extension and 1.7 mm, and the changes in the RLA and SLA were 18° and 12° from full extension, respectively. The change in the RLA correlated with the corrections of the ISA and AL. Although the change in the SLA did not correlate with either of them, the mean postoperative SLA was not significantly different from the mean value of the uninjured side. CONCLUSIONS The degree of humpback deformity of the scaphoid correlated with the degree of carpal malalignment. The corrective bone graft resulted in the expected recovery of carpal alignment according to the preoperative plan. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
While options for operative treatment of leg axis varus malalignment in patients with medial gonarthrosis include several established procedures, such as unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA) or high tibial osteotomy (HTO), there has been little focus on a less invasive option introduced more recently: the UniSpacer™ implant, a self-centering, metallic interpositional device for the knee. This study evaluates clinical and radiological results of the UniSpacer™, whether alignment correction can be achieved by UniSpacer™ arthroplasty and alignment change in the first five postoperative years. Anteroposterior long leg stance radiographs of 20 legs were digitally analysed to assess alignment change: two relevant angles and the deviation of the mechanical axis of the leg were analysed before and after surgery. Additionally, the change of the postoperative alignment was determined one and five years postoperatively. Analysing the mechanical tibiofemoral angle, a significant leg axis correction was achieved, with a mean valgus change of 4.7 ± 1.9°; a varus change occurred in the first postoperative year, while there was no significant further change of alignment seen five years after surgery. The UniSpacer™ corrects malalignment in patients with medial gonarthrosis; however, a likely postoperative change in alignment due to implant adaptation to the joint must be considered before implantation. Our results show that good clinical and functional results can be achieved after UniSpacer™ arthroplasty. However, four of 19 knees had to be revised to a TKA or UKA due to persistent pain, which is an unacceptably high revision rate when looking at the alternative treatment options of medial osteoarthritis of the knee.

Abstract
OBJECTIVE To identify hand function problems and the reasons for choosing a specific finger splint in patients with rheumatoid arthritis (RA) and swan neck deformities. METHODS A qualitative study was performed alongside a randomized, controlled cross-over trial comparing the effectiveness of two types of finger splints (the silver ring splint [SRS] and the prefabricated thermoplastic splint [PTS]) in 50 patients with RA and swan neck deformities. Questions on the patients' main hand function problem and reasons for choosing a specific splint type were performed at baseline and after using each splint. The qualitative analyses included the identification of meaning units and (sub)concepts related to hand function problems and splint preferences. RESULTS RA patients with swan neck deformities experience problems with flexion initiation, painful proximal interphalangeal joint hyperextension, grip activities and comprehensive hand function activities. Reasons for preferring or not preferring a specific type of finger splint included: effect, ease of use, appearance, comfort and side effects. Apart from the splint slipping off and a negative attitude towards the appearance of the splint, which appeared to be more frequently mentioned in connection with the SRS, no clear pattern of positive or negative appreciation of either type of splint could be distinguished. CONCLUSION RA patients with swan neck deformities experience a variety of problems, including impairments in functions and limitations in daily activities. With the prescription of finger splints, a substantial number of potentially positive and negative consequences of their use need to be taken into account.

Abstract
PURPOSE Watson and Ballet introduced the concept of a direct association between scapholunate (SL) dissociation and radioscaphoid (RS) arthritis with preservation of the radiolunate (RL) articulation in 1984. This principle has served as the anatomic, biomechanical, and pathophysiological basis for reconstructive surgery in the carpus. Recently, we have noted cases of concurrent SL dissociation and RL arthritis without RS arthritis, which is contrary to the accepted concept of wrist arthritis due to SL advanced collapse. The purpose of this study was to determine whether Watson and Ballet's thesis that SL dissociation results in RS joint degeneration with sparing of the RL joint can be confirmed, or whether another joint degeneration pattern can be associated with SL dissociation. METHODS The 3 authors independently reviewed 897 radiographs of the wrist in 691 male patients (206 bilateral and 485 unilateral) with diagnosis codes of wrist osteoarthritis (715.13), wrist instability (718.83), and wrist sprain (842.00). Posterior-anterior, oblique, and lateral views were available for all wrists. Elements assessed were RS joint, RL joint, SL joint, midcarpal joint, ulnar variance, ulnolunate joint, SL angle, and lunocapitate angle. RESULTS There were 146 wrists with radiographic SL dissociation. Nine wrists in 6 patients had radiographic SL dissociation and RL arthritis but no RS arthritis. An additional 6 wrists in 6 patients had radiographic RL arthritis but no SL dissociation or RS arthritis; however, 5 of these did have an SL angle of 60 degrees or greater. CONCLUSIONS Our results show that RL arthritis can occur in association with SL dissociation, and that the generally held view that the RL articulation is spared in SL advance collapse is not universally true. Consequently, it is our recommendation that both the RL and RS joints should be carefully evaluated for degenerative changes when planning treatment for patients with SL dissociation, because it should not be assumed that the RL joint has been spared.

Abstract
The study aimed to evaluate the degree of gleno-humeral joint deformation in children with persistent obstetric brachial plexus palsy and its effect on limb function. Computer tomography was performed in 24 children in the mean age of 6.1 years. There were eight boys and 16 girls. Gleno-scapular angle, congruency of gleno-humeral joint and joint deformity according to Waters at all. criteria were measured. The mean functional score according to the Mallet classification system was 12.3 points. The joint was stabile in nine, subluxed in seven and dislocated in nine cases. Gleno-scapular angle in affected joints was 23.3 degrees and in non-affected 4.5 degrees. The glenoid was statistically more retroverted in older children. With more severe posterior incongruence there was statistically greater limitation of passive external rotation, active internal rotation and a poorer functional result according to Mallet. Abnormalities were found also in the humeral head, being deformed and smaller compared to the non-affected side in all cases. Glenoid retroversion, posterior subluxation/dislocation of humeral head and smaller humeral head size are the abnormalities, most often identified in CT examinations. Shoulder function and in particular, passive, external rotation are closely associated with the degree of deformity of the glenoid, as well as with the extent of posterior humeral head dislocation.

Abstract
We reviewed 192 patients (224 knees) to assess the results of HTO in medial gonarthrosis during the period 1982-2008. Median follow-up was about 15 years for 134 females and 58 males. Among the knees, 118 had an average opening wedge for varus angle of 13 degrees and 106 had closing wedges of 11 degrees. Knee Society scoring before osteotomies was 68/200 for opening wedge and 81/200 for closing wedge. Modified Ahlback classification showed preoperative grades I (n = 44), II (78), III (83) and IV (19). Healing delay was 55 days for closing and 70 for opening osteotomy. Twenty-nine knees were still painful. Twenty-eight patients were revised and 19 others had complications. After opening wedge osteotomy, scoring was 101/200 and valgus angle was 2 degrees. After closing wedge osteotomy, scoring was 94/200 and valgus angle was 4 degrees. Global results were as follows: very good, 12%; good, 30%; fair, 31%; and poor, 27%. HTO decreases stresses on medial compartments and widens joint space. The average of 5 degrees mechanical valgus at the time of osteotomy seems to be quite effective at the follow-up for at least ten years. Our indications are opening wedge for grades 1-3 and wide varus angle, until the age of between 65-70. Closing wedge is indicated for medium varus in younger patients.

Abstract
In a randomised clinical trial in 50 patients with symptomatic osteoarthritis of the medial compartment of the knee, the clinical results of high tibial osteotomy (HTO) according to the open wedge osteotomy (OWO) and closed wedge osteotomy (CWO) were compared. In both groups locked plate fixation was used. Clinical and radiological assessments were performed preoperatively and after one year. Postoperative hip-knee-ankle (HKA) correction angles were monitored on standing leg X-rays. The effect of HTO on collateral laxity of the knee was measured with a specially designed varus-valgus device. The WOMAC osteoarthritis index, the modified knee society score (KS) and visual analogue scales (VAS) were used to assess symptoms of osteoarthritis, function, pain and patient satisfaction. At one-year follow-up we found accurate corrections in both groups and the planned correction angles were achieved. No loss of correction was observed. Furthermore, the medial collateral laxity and the patellar height significantly decreased after OWO. Significant improvements of WOMAC and KS scores were found in both groups. All patients had significantly less pain and were very satisfied with the results. Surgery time was significantly longer in the CWO group, and complications were more frequent in this group. Both techniques led to good and comparable clinical results. The choice of whether to perform an open or a closed wedge osteotomy may be based on preoperative patellar height or concomitant collateral laxity.

Abstract
BACKGROUND The purpose of the study was to analyze shoulder, elbow and forearm function in children with persistent obstetric brachial plexus palsy. We aimed also to evaluate relationship between age, severity of root involvement and functional deficit of affected limb. MATERIALS AND METHODS Fifty-one patients with the Mallet score less than 23 points were entered into a prospective study. Their average age was 6 years and 6 months (range from 18 months to 19 years). There were 30 boys and 21 girls. Clinical data from last follow-up was evaluated. RESULTS Average Mallet score was 17 points at last follow-up. The most common problem found in 60% of children was limitation of active external rotation of the shoulder. One forth of patients had posterior dislocation or subluxation in glenohumeraljoint. Moreover, 35.3% had significant limitation of active flexion, 37.3% had limitation of active abduction and 37.3% had limitation of internal rotation of shoulder. Limitation of active forearm pronation was found in 37% and active supination in 50% of patients. Persistent limb dysfunction (except shoulder external rotation) was dependent on root involvement but did not depend on patient's age. CONCLUSIONS Limitation of shoulder external rotation with concomitant posterior subluxation or dislocation of the glenohumeral joint is the most common finding in patients with obstetric brachial plexus palsy and does not depend on severity of root involvement, as is related to suprascapular nerve injury. The other shoulder movement are more effected in children with more severe nerve root involvement. Half of our patients had had limitation of forearm supination, what may be related to more common use of pronation in everyday activities.

Abstract
Various materials are used to fill osteotomy defects created in the medial opening wedge high tibial osteotomy (MOWHTO). Our hypothesis was that a bone allograft would provide the osteotomy site bone healing within the expected time. We performed the MOWHTO using a cancellous bone allograft in 310 knees in 284 patients between 2000 and 2005. Internal fixation was achieved with a T-profile AO plate. Preoperative and postoperative radiographic measurements were taken and statistically processed. All patients were followed up for a period ranging from three to eight years, or 5.9 years on average. Implanted cancellous bone allografts <or=9 mm healed within 12 weeks in 90% of cases. With the properly selected patient and surgical technique, use of a cancellous bone allograft in MOWHTO represents a satisfactory choice in providing bone healing.

Abstract
Authors present early results of Scorpio TS prosthesis in primary and revision total knee arthoplasty due to aseptic and septic loosening. 26 arthroplasties were performed on 25 patients. There were 19 women and 6 men of age from 37 to 80 (average 68.4 years). 11 patients from this group were operated because of septic loosening. The follow up from 2 to 22 months (average 11 months). Early results were access according to Clinical Rating System of The Knee Society: 19 patients had very good and good (73%) including primaries, 1 satisfactory (4%) and 6 poor (23%) results. The satisfactory and poor results were obtained in 7 cases with septic loosening who had had four or more previous operations on the knee. Four of them had instability of prosthesis and we changed it for MRH type. In one case due to reinfection and sepsis amputation above the knee was performed. In another patient tibia fracture below stem and loosening of tibial component occurs after 6 months of revision. ORIF gave fracture union after 8 months and exchange Scorpio TS to MRH was performed. In two cases the wound problems occurred and was solved. There were no reinfection and aseptic loosening in another cases. We didn't notice any thrombosis complications.

Abstract
The results in 53 knees that had been treated by proximal tibial opening-wedge osteotomy for large varus deformity and osteoarthritis of the medial compartment were evaluated after a mean length of follow-up of ten years (range, 8-12 years). We used a porous beta-tricalcium phosphate (beta-TCP) wedge because it is resorbable and osteoinductive. All osteotomies were completely consolidated and complete osseointegration of the remnant of the beta-TCP wedge took place. However, after a mean maximum follow-up of ten years none of the cases showed complete resorption. After ten years, 40 (81%) of the 53 knees had an excellent or good result, and in 13 knees there was recurrent pain for which six had an arthroplasty. Although the results deteriorated with time, time was not the only determinant of the result. Alignment, measured as the hip-knee-ankle angle on radiographs of the whole limb that were made with the patient bearing weight, was also a determinant of long-term results. The best results were obtained in the knees that had a hip-knee-ankle angle of 183-186 degrees. In these knees, there was no pain and no progression of the arthrosis in either the medial or the lateral tibiofemoral compartment. Of the three knees that had an angle of more than 186 degrees, all five had progressive degenerative changes in the lateral compartment. In the undercorrected knees (an angle of less than 183 degrees), the results were less satisfactory, and there was a tendency toward recurrence of the varus deformity and progression of the arthritis of the medial compartment. However, when the correction was insufficient the deterioration was slow. Therefore, proximal tibial osteotomy is a very suitable operation even for patients who have gonarthrosis of the medial compartment and a large varus deformity. Although, a rigidly standardised and precise operative technique is required as well as accurate radiographic measurements of the mechanical axis of the limb because exact postoperative alignment is the prerequisite for the longest possible period of relief of symptoms after osteotomy, and this exact alignment is difficult to obtain for patients with large varus deformity.

Abstract
OBJECTIVE To compare the effectiveness and acceptability of silver ring splints (SRS) and commercial prefabricated thermoplastic splints (PTS) in treating swan neck deformities in patients with rheumatoid arthritis (RA). METHODS Consecutive patients with RA and a mobile swan neck deformity were included in a randomized, crossover trial. In 2 different sequences, patients used both splints for 4 weeks, with a washout period of 2 weeks. Afterward, patients used the preferred splint for another 12 weeks. The primary outcome measure was dexterity measured with the Sequential Occupational Dexterity Assessment (SODA). Secondary outcome measures included other measures of hand function, satisfaction with the splints, and splint preference. RESULTS Fifty patients were included, and 47 (94%) of those completed the study. Eighteen patients (36%) had 1 swan neck deformity, whereas the other patients had 2 or more. The improvement of the total SODA score with the SRS (11.2; 95% confidence interval [95% CI] 8.1, 14.3) and PTS (10.8; 95% CI 7.5, 14.1) was similar (difference -0.5; 95% CI -2.2, 1.2). In addition, there were no significant differences in change scores regarding the other clinical outcome measures, or satisfaction. Twenty-four patients preferred the SRS, 21 preferred the PTS, and 2 patients chose neither. A comparison in the 12-week followup period yielded similar clinical outcomes, with the exception of a significantly higher score in 3 items of satisfaction in the SRS group. CONCLUSION For patients with RA and a mobile swan neck deformity, SRS and PTS are equally effective and acceptable.

Abstract
UNLABELLED Knee flexion deformity can cause marked physical disability. Acute correction, whether nonoperative or operative, may lead to serious complications. We treated 50 patients (71 knees) between 1994 and 2002 with the Ilizarov external fixator. The deformity was gradually corrected using Ilizarov principles. Of the 50 patients, 29 were affected unilaterally and 21 bilaterally. In 15 patients, there were associated deformities. In no patient did we surgically release soft tissues; in two patients with arthrodesed or congenitally fused knees, we performed osteotomy before distraction. All patients were assessed clinically and radiographically. We assessed knee flexion angle, range of motion, stability, presence of pain, and healing index. After a minimum followup of 1 year (mean 3.7 years; range, 1-8 years), 18 of 20 of the preoperatively nonambulatory patients having bilateral surgery could walk at last followup. Complications included pin tract infection in all patients, knee subluxation in three patients, and fracture related to treatment in seven patients. We believe gradual correction using a circular frame an effective method to treat flexion knee contractures. In patients with bilateral deformities, improvement in functional activity may be expected in most patients. LEVEL OF EVIDENCE Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
We report our experiences for treating the bony genu recurvatum combined with ligamentous instability that needed both osteotomy and ligament reconstruction in three cases. The bony component was corrected according to normal tibial slope, patellar height and limb length. After the osteotomy, we reevaluated the instability of the knee and performed ligament reconstruction if the patients had ligamentous instability even though the osteotomy was done.

Abstract
Jaccoud arthropathy (JA) was initially described in patients with rheumatic fever and later in several other rheumatologic conditions, particularly systemic lupus erythematosus (SLE). In patients with the latter disorder, a prevalence of about 5% has been observed. We conducted the current study to describe a series of patients with SLE with JA, followed at the Hospital Santa Izabel, Salvador, Brazil, during the year 2006. We reviewed the literature on JA, with emphasis on the histologic, clinical, radiologic, and therapeutic aspects of the condition. Twenty-one patients with JA were identified, corresponding to a prevalence of 3.47% in the population of 606 patients with the diagnosis of SLE attended in our service. Twenty patients were women, and the mean age was 40.2 +/- 8.8 years (range, 24-55 yr). The most frequently found joint deformities were swan neck and thumb subluxation, both identified in 14 patients. Ulnar deviation was seen in 8, boutonniere deformity in 3, and hallux valgus in 2 patients. We found no difference in the clinical or laboratory features in SLE patients with or without JA. The patients with JA presented a trend toward a lower quality of life compared with the patients with SLE without JA, but without statistical significance.

Abstract
Knee alignment angle, a measure of mechanical axis, has been reported to correlate with severity and progression of knee osteoarthritis. However, quantification of knee alignment often results in unacceptable reproducibility because of poor definition of landmarks and imprecise measurement techniques. We describe and validate a reproducible, sensitive method. Fourteen patients (28 knees) with symptomatic knee osteoarthritis who had full-limb radiography were evaluated. Knee alignment angle, defined as the angle formed between the mechanical axis of the femur and that of the tibia, was determined using a conventional manual technique and compared with a novel digital method using freely available Image J software to designate landmarks digitally and to determine the angles formed by the femoral and tibial axes. We found agreement between the manual and digital methods. All assessments were performed in duplicate on separate days. Using the manual method, the limits of agreement were +1.65 degrees to -1.55 degrees, yielding a minimal detectable change of approximately 1.6 degrees. However, the digital method provided limits of agreement of +0.43 degrees to -0.37 degrees resulting in a minimally detectable change of 0.4 degrees. We describe a method to reliably determine mechanical axis with precision permitting detection of differences less than 1 degrees.

Abstract
OBJECTIVE Individuals with medial compartment knee osteoarthritis (OA) and genu varum use different movement and muscle activation patterns to increase joint stability during gait. The purpose of this study was to ascertain whether opening-wedge high-tibial osteotomy (OW-HTO) corrected pathomechanical abnormalities associated with the progression of knee OA. METHODS Fifteen patients diagnosed with medial knee OA and genu varum who were scheduled for OW-HTO were tested prior to and 1 year following OW-HTO. Fifteen age- and sex-matched controls were also tested. Frontal plane laxity was measured from stress radiographs. All participants underwent quadriceps strength testing with a burst superimposition technique and gait analysis with surface electromyography to calculate knee joint kinematics and kinetics and muscle co-contraction during the stance phase of gait. Participants rated their knee function and instability using a self-report questionnaire. RESULTS Static alignment improved following the surgery. Medial laxity (P = 0.003) and instability (P = 0.002) significantly improved, and statistical reductions in the adduction moment resulted in lower levels of vastus medialis-medial gastrocnemius muscle co-contractions (P = 0.089). Despite improvements in global rating of knee function (P = 0.001), the OA group's ratings remained significantly lower than those of the healthy controls (P = 0.001). Quadriceps strength deficits and knee flexion impairments persisted. CONCLUSION Persistent quadriceps weakness and impaired knee kinematics after realignment suggest that the movement strategy may perpetuate joint destruction and impede the long-term success of realignment. Rehabilitation should focus on quadriceps strength and improving joint mobility to improve the long-term function of individuals with medial knee OA.

Abstract
Pre-existing femoral or tibial extra-articular fracture deformity may adversely affect the results of total knee arthroplasty (TKA). This deformity can be addressed with asymmetrical intra-articular resection or with correctional osteotomy performed prior to or at the time of primary TKA. Careful preoperative planning obviates many potential problems that can occur at the time of surgery with correction of many complex deformities.

Abstract
OBJECTIVE To discuss the outcomes and complications of total knee arthroplasty (TKA) for extension ankylosing deformity of the knee. METHODS From January 1996 to June 2006, total knee arthroplasty was performed on 8 patients (9 knees) with extension ankylosing deformity. The preoperative ROM of all patients was 0 degrees . Preoperative knee and function score of KSS were 44 points (from 10 to 68) and 17 points (from -10 to 55) respectively. RESULTS The complications of all TKAs included patellar tendon avulsion in 1 knee, partial fracture of inferior patella in 1 knee, hematoma in 1, superficial infection in 1. All patients were followed up for an average of 40.4 months (from 7.0 to 120.0). The average postoperative ROM was 89 degrees (from 50 degrees to 120 degrees ). Postoperative knee and function score of KSS were 81 points (from 55 to 93) and 79 points (from 50 to 90) respectively. Extension lag occurred in 2 knees, one was 10 degrees and the other was 25 degrees . One knee had undergone re-revision of changing the thicker tibial spacer for the reason of instability of joint 1 year after revision. CONCLUSIONS TKA performed in extension ankylosing deformity can get less satisfactory clinical results comparing with fixed flexion deformity. Exposure of the knee joint and separation of the fused bones, providing a mobile joint space plays crucial procedure for the next step of surgery. Preservation of sufficient bone stock of patella, protection of patellar tendon and blood supply of the knee and proper soft tissue balance are the key to TKA for extension ankylosing deformity.

Abstract
OBJECTIVE Supracondylar humerus fractures (SCHF) are common in the pediatric population. Cubitus varus deformity (CVD) is the most common long-term complication of SCHFs and may lead to elbow instability and deficits in throwing or extension. Distal fragment malrotation in the axial plane disposes to fragment tilt and CVD; however, no simple method of assessing fracture malrotation exists. This study tested a mathematical method of measuring axial plane malrotation in SCHFs based on plain radiographs. DESIGN A pediatric SCHF model was made, and x-rays were taken at known intervals of rotation. Five independent, blinded observers measured these films. Calculated rotation for each data set was compared to the known rotation. The identical protocol was performed for an aluminum phantom. RESULTS The reliability and agreement of the rotation values were good for both models. CONCLUSIONS This method is a reliable, accurate, and cost-effective means of calculating SCHF distal fragment malrotation and warrants clinical application.

Abstract
Fixed flexion deformity of the knee is one of the commonest deformities that occur as a secondary complication of various knee arthropathies. In developing countries such as India, where walking is the primary, preferred and most feasible mode of transport, the secondary complications following a fixed flexion deformity of the knees pose a serious threat to functional independence. External splinting techniques have been in use for many years for preventing and correcting fixed flexion deformities, but most of the splinting methods commonly used have disadvantages. Static splinting leads to a reduction in the range of movement and muscle strength due to prolonged immobilization; traction techniques restrict the patient to bed and necessitate hospitalization. Wedge casting can lead to a posterior subluxation of the tibia when used over a long period. Thus, the idea was to design an orthosis that serves the purpose of improving knee range of movement without the above-mentioned complications, at the same time being portable and comfortable to the client, concomitantly allowing them to be ambulant. Accordingly this article presents a new method in splinting that helps in these multiple ways.

Abstract
Because the femoral head/neck junction is preserved in hip resurfacing, patients may be at greater risk of impingement, leading to abnormal wear patterns and pain. We assessed femoral head/neck offset in 63 hips undergoing metal-on-metal hip resurfacing and in 56 hips presenting with non-arthritic pain secondary to femoroacetabular impingement. Most hips undergoing resurfacing (57%; 36) had an offset ratio ≤ 0.15 pre-operatively and required greater correction of offset at operation than the rest of the group. In the non-arthritic hips the mean offset ratio was 0.137 (0.04 to 0.23), with the offset ratio correlating negatively to an increasing α angle. An offset ratio ≤ 0.15 had a 9.5-fold increased relative risk of having an α angle ≥ 50.5°. Most hips undergoing resurfacing have an abnormal femoral head/neck offset, which is best assessed in the sagittal plane.

Abstract
Internal rotation gait is common in children with cerebral palsy. Factors thought to contribute include femoral anteversion, hip flexor tightness, imbalance of hip rotators, and hamstring and adductor tightness. The exact cause of internal rotation must be defined before contemplating surgery. We investigated the prevalence of internal hip rotation and associated factors, which are considered to influence this walking pattern, in patients with cerebral palsy. Gait laboratory data of 222 patients with cerebral palsy were studied retrospectively. Two groups were selected; those with maximum dynamic hip internal rotation of more than 27 degrees and those with less than 20 degrees. Of 222 patients, 27.0% (diplegia, 61.7%; hemiplegia, 38.3%) had at least one hip with dynamic internal rotation of more than 27 degrees. This study suggests that dynamic hip internal rotation is multifactorial in origin. The most significant differences in clinical measures were found in values of passive hip external rotation range, femoral anteversion and hip flexor contracture. We discuss the role of early treatment of hip flexion contracture.

Abstract
PURPOSE Tibial osteotomy is used to treat a variety of orthopedic conditions, including reduction in pain and improvement of deformity and function. In templating for surgery, accurate radiographic measurement aids in planning for correction. The purpose of our study was to examine the effect of internal rotation and external rotation on measurement of tibial sawbone models with 5 closing wedge varus deformities at 10-degree increments between 10 and 50 degrees. One sawbone without deformity served as the control. STUDY DESIGN A total of 66 radiographs were measured by 5 individuals. Measurement deviations from the control in each of the 10 positions of rotation were assessed. RESULTS In the analysis of variance models, increased rotation and varus angulation were associated with increased deviation compared with the control. In external rotation for every 10 degrees of varus angulation, the degree deviation increased 0.69 degrees. In IR for every 10 degrees of angulation, the degree deviation increased by 0.84 degrees. Internal rotation had the greatest impact. Mean differences between different rater's measurements were small (1.1+/-1.2 degrees) and correlations suggested high interrater reliability. CONCLUSIONS As the degree of rotation from neutral increased and varus angulation increased, deviation from neutral increased. CLINICAL RELEVANCE Clinically, the results of this study support the importance of proper alignment of the tibia during radiography to more precisely template surgery.

Abstract
BACKGROUND High tibial osteotomy has been associated with significant complications, including delayed union or nonunion, loss of correction, arthrofibrosis, and patella infera. HYPOTHESES A technique for opening wedge osteotomy that incorporates an autogenous iliac crest bone graft will prevent delayed union or nonunion, allow early rehabilitation and weightbearing, and prevent knee arthrofibrosis and patella infera. Secondly, the authors' methods for calculating the desired correction of valgus alignment prevent undesired alterations in tibial slope. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 55 consecutive patients who underwent high tibial osteotomy were observed at a mean of 20 months postoperatively. Preoperative and postoperative measurements of radiographs were conducted by independent examiners for bony union, tibial slope, and patellar height. The osteotomy opening size ranged from 5 to 17.5 mm; 35 knees (64%) had openings < or =10 mm, and 20 knees (36%) had openings >11 mm. RESULTS The osteotomy united in all patients. Three patients had a delay in union, which resolved by 6 to 8 months postoperatively. A loss of fixation occurred in 1 patient, who admitted to full weightbearing immediately after surgery; the osteotomy required revision. The iliac crest graft site healed without complications, and there were no infections, loss of knee motion, nerve or arterial injuries, alterations in tibial slope, or cases of patellar infera postoperatively. Full weightbearing was achieved at a mean of 8 weeks (range, 4-11 weeks) postoperatively. CONCLUSIONS The operative technique including use of an autologous iliac crest bone graft in addition to a progressive rehabilitation program successfully prevented nonunion, change in tibial slope, and knee arthrofibrosis in this study.

Abstract
We studied 11 patients (14 elbows) with gross rheumatoid deformity of the elbow, treated by total arthroplasty using the Kudo type-5 unlinked prosthesis, and who were evaluated between five and 11 years after operation. Massive bone defects were augmented by autogenous bone grafts. There were no major complications such as infection, subluxation or loosening. In most elbows relief from pain and stability were achieved. The results, according to the Mayo Elbow Performance Score, were excellent in eight, good in five and fair in one. In most elbows there was minimal or no resorption of the grafted bone. There were no radiolucent lines around the stems of the cementless components. This study shows that even highly unstable rheumatoid elbows can be replaced successfully using an unlinked prosthesis, with augmentation by grafting for major defects of bone.

Abstract
The mechanical effects of genu valgum and varum deformities on the subtalar joint were investigated. First, a theoretical model of the forces within the foot and lower extremity during relaxed bipedal stance was developed predicting the rotational effect on the subtalar joint due to genu valgum and varum deformities. Second, a kinetic gait study was performed involving 15 subjects who walked with simulated genu valgum and genu varum over a force plate and a plantar pressure mat to determine the changes in the ground reaction force vector within the frontal plane and the changes in the center-of-pressure location on the plantar foot. These results predicted that a genu varum deformity would tend to cause a subtalar pronation moment to increase or a supination moment to decrease during the contact and propulsion phases of walking. With genu valgum, it was determined that during the contact phase a subtalar pronation moment would increase, whereas in the early propulsive phase, a subtalar supination moment would increase or a pronation moment would decrease. However, the current inability to track the spatial position of the subtalar joint axis makes it difficult to determine the absolute direction and magnitudes of the subtalar joint moments.

Abstract
BACKGROUND Internal rotation contractures due to external rotation weakness secondary to brachial plexus birth palsy frequently lead to glenohumeral deformity and impaired shoulder function. Our surgical approach to treat these contractures relies on arthroscopic release for young children (less than three years old) and combines arthroscopic release with latissimus dorsi transfer for older children. We report the results for the first thirty-three children followed for a minimum of two years after such treatment. METHODS Nineteen children with a mean age of 1.5 years (all younger than three years of age) underwent arthroscopic contracture release as the only primary procedure, and fourteen children with a mean age of 6.7 were also treated with a latissimus dorsi transfer. Passive external rotation with the arm at the side and passive and active elevation were measured for all patients preoperatively. Passive and active external rotation, internal rotation, and elevation were measured for all patients postoperatively. Magnetic resonance imaging was performed preoperatively and postoperatively to evaluate the status of the glenohumeral joint. RESULTS Preoperative passive external rotation averaged -2 degrees for the children who underwent arthroscopic contracture release only and -24 degrees for those who also were treated with a latissimus dorsi transfer. Arthroscopic release achieved a marked increase in passive external rotation and a centered position of the glenohumeral joint at the time of surgery in all but the oldest child in the series, who had severe deformity. The contracture recurred in four of the younger children who had an isolated release, and this was treated with a repeat arthroscopic release and a secondary latissimus dorsi transfer. None of the children who had a primary latissimus dorsi transfer had recurrence of the contracture. At the time of follow-up, the mean passive external rotation was increased by 67 degrees (p < 0.005) in the fifteen children with a successful arthroscopic release, 81 degrees (p < 0.005) in those treated with a primary latissimus dorsi transfer, and 78 degrees in the four patients who were treated with a late latissimus dorsi transfer because the isolated arthroscopic release failed. The mean active elevation increased 12 degrees , 3 degrees , and 10 degrees , respectively, in the three groups. Internal rotation was not measured consistently preoperatively, but when it had been it was found to have decreased substantially postoperatively. Magnetic resonance imaging performed prior to the surgery showed a pseudoglenoid deformity in eighteen of the children. At two years, magnetic resonance images were available for fifteen of those children, and twelve of the images showed marked remodeling of the deformity. CONCLUSIONS In children who are younger than three years of age, arthroscopic release effectively restores nearly normal passive external rotation and a centered glenohumeral joint at the time of surgery. In most of these children, external rotation strength is sufficient to maintain this range of motion and to improve glenoid development when preoperative deformity was present. The addition of a latissimus dorsi transfer in older children predictably results in similar improvements. Gains in active elevation are minimal. All children have a loss of internal rotation, which is moderate in most of them but is severe in some.

Abstract
Between July 2000 and April 2004, 19 patients with bilateral spastic cerebral palsy who required an assistive device to walk had combined lengthening-transfer of the medial hamstrings as part of multilevel surgery. A standardised physical examination, measurement of the Functional Mobility Scale score and video or instrumented gait analysis were performed pre- and post-operatively. Static parameters (popliteal angle, flexion deformity of the knee) and sagittal knee kinematic parameters (knee flexion at initial contact, minimum knee flexion during stance, mean knee flexion during stance) were recorded. The mean length of follow-up was 25 months (14 to 45). Statistically significant improvements in static and dynamic outcome parameters were found, corresponding to improvements in gait and functional mobility as determined by the Functional Mobility Scale. Mild hyperextension of the knee during gait developed in two patients and was controlled by adjustment of their ankle-foot orthosis. Residual flexion deformity > 10° occurred in both knees of one patient and was treated by anterior distal femoral physeal stapling. Two children also showed an improvement of one level in the Gross Motor Function Classification System.

Abstract
Spondyloepimetaphyseal dysplasia (SEMD) Strudwick type is a rare autosomal dominant condition arising from defects in COL2A1 the genes responsible for the biosynthesis of procollagen type II. The orthopaedic manifestations of patients can be hypoplastic odontoid peg with atlantoaxial instability, severe kyphosis or lordosis of dorsal and lumbar spines, hip subluxation, coxa vara and early severe hip osteoarthritis, and malalignment of lower limbs like genu valgum or club foot. We report a mother and daughter with SEMD Strudwick Type and describe their orthopaedic problems, surgical management and clinical outcome after 30 years and 7 years of follow-up respectively.

Abstract
BACKGROUND Hip dysplasia is considered pre-osteoarthritic, causing degeneration in young individuals. OBJECTIVE To determine the pattern of degenerative change in moderate to severely dysplastic hips in young patients. DESIGN AND PATIENTS One hundred and ninety-three consecutively-referred younger patients with hip pain believed to be caused by hip dysplasia constituted the study cohort. The average age was 35.5 years (range, 15-61 years). They were examined by close-cut transverse pelvic and knee computed tomography and antero-posterior radiographs (CT). We identified 197 hips with moderate to severe dysplasia, and 78 hips with normal morphology in the study cohort, whilst 111 hip joints were borderline dysplastic according to preset definitions. Comparative analyses of anatomy and distribution of degeneration between dysplastic and normal hips in the study cohort were performed. RESULTS In dysplastic hips the anterior acetabular sector angle was significantly and inversely associated to femoral anteversion (p < 0.001). The center-edge (CE) angle, the acetabular angle (AA), and the acetabular depth ratio (ADR) were significantly interrelated (p < 0.001; correlation coefficients ranging from -0.8 to 0.7). Fifty-one hips were subluxated (24R/27L). There were no cases of complete dislocation. The formation of subchondral cysts or osteophytes in dysplastic hips was significantly associated with reduced minimum joint space width (p ranging from 0.005 to 0.02). However, in 67 hips with acetabular cysts, only 6 hips had minimum joint space widths = 2.0 mm (8.9%) in the coronal plane. In 96 cases with acetabular cysts found in the sagittal plane, 43 cases had minimum joint space widths = 2.0 mm (44.7%). Bony rim detachment at the site of labral insertion was recorded in 30 hips. Twenty-three of these were dysplastic (p = 0.01). CONCLUSIONS Degeneration was most often found in the anterolateral part of the dysplastic hip joints. Most cysts were located above the transition zone between the bony and the fibrocartilaginous acetabulum, and we found a significantly- increased number of cases with avulsed bony fragments at the antero-lateral labral insertion in dysplastic hips compared to normal hips. It seems likely that the early degenerative process in dysplastic hips originates at the watershed zone between the acetabular labrum and the acetabular cartilage in response to subluxation and femoroacetabular impingement.
