Prediction of disability in trigger finger: a cross-sectional and longitudinal study

The aim of this prospective study of 55 patients was to analyse the cross-sectional and longitudinal relationship between disability and physical and psychological variables after conservative treatment of trigger finger and to determine the predictive factors for the post-treatment disability score and change in disability score. The primary outcome measure was the Disabilities of the Arm, Shoulder, and Hand questionnaire. Potential predictive factors included pain, number of triggering events, depression, anxiety and kinesiophobia. Disability correlated strongly with anxiety, moderately with pain and depression and weakly with triggering and kinesiophobia. The change in depression score correlated significantly with the change in disability score. Post-treatment pain and anxiety scores accounted for 47% of the explained variance in disability score. Improvement in depression after treatment accounted for 18% of the explained variance in disability change score. Psychological variables appear to be potential predictors of disability.Level of evidence: IV.

Epithelioid Sarcoma-like Hemangioendothelioma a Case Report

Seven cases of an unusual low-grade vascular tumor were reported in a recent study. Despite its similarity to epithelioid sarcoma, this tumor was termed epithelioid sarcoma-like hemangioendothelioma because of the subtle histopathological and immunohistochemical differences. Another case of this rare entity in a 70-year-old woman who suffered from a painful mass on the anterior aspect of the right cubital fossa is presented here, together with a review of the relevant literature.

Metatarsal transfer for the treatment of post-axial metatarsal-type foot synpolydactyly: a new technique that allows for comfortable shoe wearing

We analysed the clinical and radiological outcomes of a new surgical technique for the treatment of heterozygote post-axial metatarsal-type foot synpolydactyly with HOX-D13 genetic mutations with a mean follow-up of 30.9 months (24 to 42). A total of 57 feet in 36 patients (mean age 6.8 years (2 to 16)) were treated with this new technique, which transfers the distal part of the duplicated fourth metatarsal to the proximal part of the fifth metatarsal. Clinical and radiological assessments were undertaken pre- and post-operatively and any complications were recorded. Final outcomes were evaluated according to the methods described by Phelps and Grogan. Forefoot width was reduced and the lengths of the all reconstructed toes were maintained after surgery. Union was achieved for all the metatarsal osteotomies without any angular deformities. Outcomes at the final assessment were excellent in 51 feet (89%) and good in six (11%). This newly described surgical technique provides for painless, comfortable shoe-wearing after a single, easy-to-perform operation with good clinical, radiological and functional outcomes.

Primary extracranial meningioma of the lower limb

This paper is about a primary extracranial meningioma case of a 40-year-old male patient who presented with a complaint of a rapidly growing painless stiff mass located in his left thigh. The magnetic resonance imaging examination revealed that the lesion was well-circumscribed and with isosignal intensity to muscle on T1-weighted images and with a relatively hiperintense on T2-weighted images. The histopathological analysis of the specimens both from the incisional biopsy and the excisional surgery were typical of meningioma showing spindle cell proliferation with a whirling pattern. Although extracranial meningiomas are very rare, it should be considered in the differential diagnosis of a spindle cell neoplasm.

Talonavicular joint approach to the talar body: a cadaver study

BACKGROUND

Lesions of the talar dome or tumors within the talar body may require an open approach with medial or lateral malleolar osteotomies. The aim of this study was to evaluate the possibility and feasibility of a new minimally invasive approach without osteotomy, using the talonavicular joint (TJ) as the entry portal for lesions of the talar body.

MATERIALS AND METHODS

Nine cadaveric feet were used for this study. Using the TJ and a 5-mm skin incision we aimed to reach the superolateral, superomedial, inferolateral and inferomedial corners of the talar body under fluoroscopy. A 2-mm Kirshner wire and a 4-mm cannulated drill bit were used to reach the desired target area and an angled curette was used for curettage after reaching the target. The proximity of vascular structures to the entry portal was noted. The talar and navicular joint surfaces were checked for any damage. The articular areas of the talar heads and the defect areas were measured.

RESULTS

All 4 targets and even the posterior talus could be reached by this approach. The nearest neurovascular structures were the saphenous vein and the saphenous nerve. The navicular cartilage was not damaged in any specimen. The talar defect area corresponded to only 3.3% of the talar head cartilaginous area.

CONCLUSION

The TJ approach can be used to reach lesions in all regions of the talar body without the need for an osteotomy. A mini-incision may be used to retract the saphenous nerve and vein. Damage to the talar head cartilage is minimal with this approach which requires no special equipments.

CLINICAL RELEVANCE

This study shows that talar dome lesions can be reached with a minimally invasive method.

Association of Hypospadias with Hypoplastic Synpolydactyly and Role of HOXD13 Gene Mutations

OBJECTIVES

To present the association of hypospadias with hypoplastic synpolydactyly and discuss the molecular genetic basis of these conditions.

METHODS

A large synpolydactyly kindred first described in 1995 was reinvestigated. Affected and unaffected subjects were interviewed, and pedigrees of the most recent generations were constructed. The marriages of two affected individuals were identified. The siblings who were homozygous for the deformity were asked to attend our institution and underwent a detailed clinical evaluation. Genetic studies and mutation screening were performed using polymerase chain reaction on genomic DNA extracted from venous blood.

RESULTS

Of the 245 members of the kindred, 125 individuals were affected. Of these 125 individuals, 12 were homozygotes (6 females and 6 males) with a mean age of 12 years. The remaining 113 individuals (57 females and 56 males) were heterozygotes showing milder limb deformities. No sex-related phenotypic difference was found in the extremity findings, but all the males with a homozygote pattern had hypospadias. Three had distal penile, two had mid-shaft, and one had penoscrotal hypospadias. Of the affected 56 heterozygote males, 22 were also noted to have distal hypospadias in various forms. Neither the heterozygote nor the homozygote females had any genital anomalies. The laboratory tests and karyotype profiles of these individuals were normal. Mutation screening of the homozygote subjects revealed a polyalanine duplication band of nine additional alanine residues at the human HOXD13 gene.

CONCLUSIONS

These findings strongly suggest that specific mutations in HOXD13 gene may cause both hypoplastic synpolydactyly and hypospadias.

Use of a splint following open carpal tunnel release: a comparative study

This study was undertaken to compare the clinical effectiveness and costs of postoperative splintage and late rehabilitation with a bulky bandage dressing versus early rehabilitation after carpal tunnel release. In this comparative study, 46 patients were randomly divided into 2 groups. In each group, 3 patients were excluded because of improper follow-up, leaving a total of 40 patients. Group 1 used a splint (exercises given 3 wk postoperatively) and group 2 was given a bulky bandage (exercises provided immediately) after open release. Patients were assessed preoperatively and at the first and third postoperative months with the Questionnaire of Levine for Clinical Assessment of Carpal Tunnel Syndrome. The 2 groups were similar in terms of preoperative functional status scores and in controls at the first and third months (P=.549, P=.326, P=.190). When both groups were compared, no statistical significance was found regarding symptom severity scale scores preoperatively and at the first postoperative month (P=.632 vs P=.353). At the third month, scores were lower in favor of group 2 (P=.023). Additionally, 16 of 20 patients (80%) in group 1 reported a heavy feeling and discomfort caused by the splint. This problem was not reported by the patients in group 2. The cheapest splint on the market was 9 times more expensive than a bulky dressing. The investigators concluded that postoperative immobilization with a splint has no detectable benefits. Use of bulky dressings and abandonment of the use of postoperative splints may prevent unnecessary expenditures without sacrificing patient comfort or compromising the course of healing in carpal tunnel surgery.

Augmentation vs Nonaugmentation Techniques for Open Repairs of Achilles Tendon Ruptures with Early Functional Treatment: A Prospective Randomized Study

A prospective randomized study was conducted in order to compare augmentation technique versus nonaugmentation technique, followed by early functional postoperative treatment, for operative repair of Achilles tendon ruptures. Twenty-four consecutive patients were assigned to two groups. Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair. Thereafter, these patients had postoperative management with a below-knee-cast for three weeks. The physioteraphy was initiated immediately after the cast was removed. Full weight bearing was allowed after five weeks postoperatively in the both groups. Two patients had reruptures in group II, whereas group I had prolonged operative time significantly. The patients with reruptures underwent reoperations and at the most final follow-up, it was observed that they could not resume to sporting activities. The other objective and subjective results were similar between two groups. Because of quite high rerupture rate in the group of patients treated with nonaugmentation technique, we favor functional postoperative treatment with early ankle movement in the patients treated with augmentation technique for the management of acute rupture of the Achilles tendon. Key PointsA prospective randomized study was conducted in order to compare augmentation technique versus nonaugmentation technique, followed by early functional postoperative treatment, for operative repair of Achilles tendon ruptures.Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair.Functional postoperative treatment with early ankle movement in the patients treated with augmentation for the management of acute rupture of the Achilles tendon is recommended.

Synpolydactyly of the foot in homozygotes

In 2002, we reinvestigated a large synpolydactyly kindred first described in 1995. It was found to have expanded with an increase in number of homozygous offspring. These homozygotes had severe hypoplasia, with synpolydactyly of their hands and feet. We present the clinical, genetic, and surgical findings of this deformity and the histologic findings of the removed bones of the heterozygous and homozygous members. There were 125 affected individuals (113 heterozygotes and 12 homozygotes) of 245 members of the past five generations. We identified seven marriages in which both spouses were affected. Twelve offspring from these marriages had homozygote genetic patterns, hypoplastic synpolydactyly of the hands, and a distinctive foot deformity, with a prominent great toe and syndactylized hypoplastic minor toes. From clinical and surgical perspectives, their hand and foot deformities were different from those of their parents. We surgically treated both feet of four individuals with this deformity, which we called "homozygote foot synpolydactyly." Clinically, the deformity consisted of a supinated prominent great toe, hypoplastic and severely synpolydactylized minor toes, and secondary problems. Radiographically, the bones were underdeveloped, unshaped, and largely fused. Abundant cartilage covering the bones was observed surgically and histologically. Genetically, analysis of HOXD13 identified a 27-base pair duplication with a homozygote pattern. The foot deformity of the homozygotes was so distinctive and complicated that it should be considered a separate foot synpolydactyly type--homozygote foot synpolydactyly.

Factors that affect the healing index of metacarpal lengthening: a retrospective study

PURPOSE

To determine factors that affect healing index and consolidation time following lengthening of congenitally short metacarpals (brachymetacarpia).

METHODS

18 metacarpals of 8 young women (mean age, 18.6 years) were lengthened using the callus distraction technique. The results, including healing index and consolidation time, were analysed and compared with those in the literature.

RESULTS

The mean length increase was 16.5 mm (55% of the original length of 30 mm). Age was positively correlated with healing index and consolidation time: younger patients healed faster than older patients. Healing index differed significantly between patients aged 0 to 18 years and those aged 19 to 30 years (p=0.002). Comparison of our results with 9 previous studies confirmed that increased age was associated with a greater healing index and consolidation time. Conversely, the faster the distraction rate, the less the healing index and consolidation time.

CONCLUSION

Age has the most effect on healing index and consolidation time. Metacarpal lengthening using callus distraction is recommended. Adolescence is the most appropriate time to perform distraction lengthening of a congenitally short metacarpal. This will avoid additional lengthening of normal metacarpals prior to epiphyseal closure.

[Relationship between the mechanical and anatomic axis and orientation angles of the knee joint and functional capacity of patients with osteoarthritis]

OBJECTIVES

We investigated the relationship between the mechanical-anatomic axes and angles of the knee joint and functional levels of patients with primary osteoarthritis.

METHODS

A total of 35 patients (27 females, 8 males; mean age 58+/-9 years; range 42 to 77 years) with knee osteoarthritis were included. After physical examination, weight-bearing anteroposterior x-rays of the knees were obtained, on which measurements of the following were made: mechanical axis deviation (MAD), medial proximal tibial angle (MPTA), anatomic tibiofemoral angle (aTFA), mechanical lateral distal femoral angle (mLDFA), and joint line congruence angle (JLCA). Pain was evaluated by both the Western Ontario McMaster Osteoarthritis Index (WOMAC) and a visual analog scale (VAS). Functional capacity was assessed using the physical function and global indices of WOMAC.

RESULTS

There was a moderate correlation between body mass index and the WOMAC global index (r=0.47, p<0.05). Radiographic evaluations revealed varus deformity in 28 patients. There was a correlation between aTFA and the physical function (r=0.47) and global (r=0.41) indices of WOMAC (p<0.05). Functional capacity and pain were not correlated with the other mechanical angles of the knee joint (p>0.05).

CONCLUSION

In view of our results, aTFA may be considered one important criterion in designing treatment and planning surgery for patients with primary osteoarthritis.

Posterior Fixation of Thoracolumbar Burst Fracture

OBJECTIVE

The treatment of thoracolumbar burst fracture is a controversial issue. Short-segment (SS) pedicle fixation has become a popular treatment option. However, there are several studies regarding the high rate of failure. The aim of this prospective study was to compare SS versus long-segment (LS) instrumentation.

METHODS

For this purpose, 18 consecutive patients were assigned to two groups. Group 1 included nine patients treated by SS pedicle fixation, whereas group 2 included nine patients treated by LS instrumentation. SS instrumentation was pedicle fixation one level above and below the fractured vertebra. LS instrumentation was hook fixation (claw hooks attached to second upper vertebra and infralaminar hooks attached to first upper vertebra) above and pedicle fixation (pedicle screws attached to first and second lower vertebrae) below the fractured vertebra.

RESULTS

As a result, measurements of local kyphosis, sagittal index, and anterior vertebral height compression showed that the LS group had a better outcome at final follow-up (P < 0.05). Also, the SS group had a 55% failure rate, whereas the LS group had prolonged operative time and increased blood loss. However, there was no difference between the two groups according to Low Back Outcome Score.

CONCLUSIONS

In conclusion, radiographic parameters demonstrated that LS instrumentation is a more effective management of thoracolumbar burst fractures. Nevertheless, clinical outcome was the same between the two groups. However, our conclusions were based on posterior-only surgery. Anterior column support would negate the need for LS fixation. Also, SS would have been more successful if two above and two below pedicle screws were used.

The innervation of patella: anatomical and clinical study

As much interest has been focused on afferent innervation of knee than that of patella, there are few articles about patellar innervation. But in clinical practice anterior knee pain due to patellar disorders is a quite frequent problem. Our aim was to review the innervation pattern of patella and to give the topographic anatomy of the nerves. We dissected 30 knees of 15 formaldehyde-fixed cadavers. Two nerves from vastus medialis and lateralis were found to reach patellar edge. Apart from these, we were unable to find any other neural structures around patellae. Mean distances between the tuberosity of the tibia and medial and lateral nerve entry points were 90.1(range 74-102) and 96.3 mm (range 76-109), respectively. The angles between lines which join the entry points of nerves and vertical line to the center point of patella were measured in frontal plane. It was approximately 60 degrees medially and 40 degrees laterally. To confirm that these nerves are patellar pain afferents, we performed a local anesthesia test in 32 knees of 20 patients with patellofemoral pain. Clinically, there was a significant difference between the visual analogue scale (VAS) scores before and after local anesthetic injections (p<0.01). Previous studies have emphasized especially the medial innervation. We found that both superomedial and superolateral nerves were important for patellar innervation. We described precisely the entry points of these nerves to patella for selective denervation.

Radiographic evaluation and unusual bone formations in different genetic patterns in synpolydactyly

OBJECTIVE

To compare the radiological findings of heterozygous and homozygous subjects with synpolydactyly (SPD) and to discuss their unusual bone formations.

DESIGN AND PATIENTS

Families with hand and foot SPD were examined. Genetic analysis was performed with blood samples and the pedigree was constructed. The affected individuals, especially those with distinctive phenotypic features, were invited to our orthopaedics clinic for further diagnostic studies. All participants underwent detailed clinical and X-ray examinations.

RESULTS

Of the invited patients, 16 (five female and 11 male; age range 4-37 years, mean age 10.75 years) were included in our study, and hand and foot radiographs were obtained. All subjects had bilateral hand radiographs (32 hands), and 14 had bilateral foot radiographs (28 feet). Genetic analysis revealed 12 heterozygote (75%) and four (25%) homozygote phenotypes. Among patients enrolled into the study nine (three homozygotes, six heterozygotes) had SPD of both hands and feet bilaterally (tetrasynpolydactyly). Six unusual bone formations were observed in the hands and feet: delta phalanx, delta metacarpal/metatarsal, kissing delta phalanx, true double epiphysis, pseudoepiphysis and cone-shaped epiphysis. There were major differences in radiological and clinical manifestations of homozygote and heterozygote phenotypes. The homozygous SPD presented with very distinctive unusual bone formations.

CONCLUSION

The existence and variety of unusual bones may indicate the severity of penetrance and expressivity of SPD.

Hypoplastic synpolydactyly as a new clinical subgroup of synpolydactyly

A large kindred which was first described in 1995 was investigated again. We present the clinical, radiological, genetic and surgical findings of the hand deformities found in homozygote individuals which we called "hypoplastic synpolydactyly". There were 125 affected (heterozygote or homozygote) people out of 245 subjects in the five last generations. We identified seven marriages of two affected people. Twelve offsprings, of these marriages had a homozygote genetic pattern and "hypoplastic synpolydactyly". From both the clinical and surgical perspectives, their hand deformity was distinctive from that of their parents. We surgically treated both hands of three individuals with this deformity. The hand deformity of these homozygotes was so complicated and distinctive that it can be evaluated as a new subgroup of synpolydactyly.

[Familial glomus tumor encountered in the same finger and localization in four family members]

A 35-year-old man was referred to our clinic by a neurosurgeon for hypersensitivity and severe pain in his right middle finger. History showed that the symptoms had been present for three years and he had made several attempts to seek medical attention. A sensitive, very painful mass was palpated under the eponychium of his right middle finger. The tumor was surgically removed and histological examination confirmed the clinical diagnosis of a glomus tumor. Inquiry into the family history revealed that the same problem existed in the same localization with similar complaints in the father and two daughters. Both the records of the father's operation 10 years before and clinical-radiological findings of the daughters were consistent with a familial entity. In the presence of hypersensitivity and pain in the finger, family members should be inquired and a diagnosis of familial glomus tumor should be considered.

Factors affecting recurrence rate of ingrown toenail treated with marginal toenail ablation

This retrospective study analyzed marginal toenail ablation for ingrowing toenails and the factors affecting recurrences. Recurrence was defined as a return of the previous symptoms, regrowth of the nail edge, or patient dissatisfaction with the clinical outcome. Based on these criteria, nine patients (10.7%) were considered to have had a failed operation. There were significant differences for recurrence rate (p <.05) in the patients operated on under local anesthesia and in previously treated patients. Full exposure and excision of the germinal matrix were essential to avoid recurrence.

[The prevalance of orthopedic disabilities in the district of Cay, Afyon, Turkey]

OBJECTIVES

Data were collected on disabilities from a sample population in order to estimate the prevalence of orthopedic disabilities in the general population.

METHODS

A two-stage field study was conducted in Cay, a district of Afyon, Turkey. In the first stage, a list of all individuals with orthopedic disabilities was derived. Then, medical histories were elicited and examinations were made by a team of specialists of orthopedics and traumatology. Radiographic studies were made when necessary. Orthopedic disabilities were defined as any muscle or skeletal abnormality that was associated with a permanent functional loss and were classified as congenital, traumatic, cerebral palsy, poliomyelitis, and other causes.

RESULTS

The overall population was 35,571, of whom 189 had orthopedic disabilities (53/10,000). The male-to-female ratio was 1.8. The most common cause was congenital diseases (25.9%; 13.7/10,000), followed by trauma (23.8%; 12.6/10,000), cerebral palsy (21.7%; 11.5/10,000), poliomyelitis (10.1%; 5.3/10,000), and others (18.5%; 9.8/10,000). The lowest mean age (19+/-5 years) was found in those with cerebral palsy, which was associated with the highest degree of functional loss. The mean age in patients with poliomyelitis was 29+/-7 years. It was found that 37% of the disabled could benefit from either a limited or extensive surgical intervention, and 9% could have significant improvement both in functional ability and life quality through physical therapy or the use of a prosthesis/orthosis. Only 18% were under the coverage of a health insurance, though.

CONCLUSION

The data of this study may throw some new light on the prevalence and implications of orthopedic disabilities in Turkey.
