Abstract
AIM The aim of the research was to determine the smallest amount of loading on the lunate bone obtained by gradually shortening the radius in different ulnar variants as the potential treatment of Kienböck's disease. METHODS The research was conducted on anatomic preparations of 20 upper extremities using only the distal part of the forearm and hand, placing them in exactly defined positions. A Fuji Prescale film was inserted in the open radiocarpal joint to measure pressure after compressing axially by changing the length of forearm in four stages by the gradual shortening of the radius. RESULTS The greatest reduction of average pressure on the lunatum achieved by shortening the radius depended on ulnar variant. In ulnar variant 0, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 3 mm (24% reduction). For ulnar variant -1, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 2 mm (37% reduction). For ulnar variants -2, -3 and +1, the greatest reduction of average pressure on lunatum was achieved by shortening the radius for 3 mm (5%, 75% and 9% respectively). CONCLUSIONS The pressure distribution in the distal radiocarpal joint is vital for healing, and shortening of the radius relieves the pressure on the lunate bone. The exact type of surgery and the amount of radial osteotomy depends on preoperative ulnar variant.

Abstract
UNLABELLED We carried out a retrospective study to analyse the long-term outcome of 36 patients after radial shortening osteotomy for treatment of Lichtman Stage IIIA Kienböck disease at a mean follow-up of 12.1 years (range 5.4-17.5). At review, seven wrists had progressed to Stage IIIB, eight wrists to Stage IV and 21 remained in Stage IIIA. Motion and grip strength were significantly improved. The mean Disabilities of the Arm, Shoulder, and Hand (DASH) score at review was 12 points (range 0-52), and patient satisfaction was high. Apart from plate removals in 14 patients and one wrist denervation, no subsequent surgical procedures were done. Radial shortening yields good long-term clinical results, but does not prevent radiographic progression of disease in some patients. LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Vascularized bone grafts for the treatment of Kienböck's disease may facilitate revascularization and remodeling of the avascular lunate. The aim of this study was to evaluate the radiological and clinical results obtained when a fourth extensor compartmental artery (ECA) bone graft was used to treat Kienböck's disease. METHODS Between May 2009 and June 2012, 13 patients (6 men, 7 women) with Kienböck's disease were treated with placement of fourth ECA vascularized bone grafts. The mean patient age was 39.2 (20-58) years, and the mean follow-up period was 32.5 (12-72) months. At the time of surgery, One patient had Lichtman's stage II Kienböck's disease, 11 stage IIIA disease, and one stage IIIB disease. We measured the pre- and post-operative ranges of motion, pain, grip strength, and radiological parameters, including the carpal height ratio and the radioscaphoid angle. RESULTS At the last follow-up, pain was significantly reduced, and grip strength had improved from 60.5% to 87.8% relative to that of the contralateral side. The mean range of motion for flexion had improved from 39° to 53° while that of wrist joint extension improved from 41° to 56°. There were little or no changes in either the carpal height ratio or the radioscaphoid angle (both p values > 0.05). CONCLUSIONS Placing of a fourth ECA vascularized bone graft is a reliable alternative to other revascularization procedures for treatment of Kienböck's disease. Such grafting is effective, minimally invasive, and associated with a low risk of pedicle kinking. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic/IV.

Abstract
PURPOSE To analyze the outcomes of lunate excision combined with scaphotrapeziotrapezoid arthrodesis for the treatment of advanced Kienböck disease. METHODS Sixteen patients with Lichtman stage IIIB Kienböck disease were treated with scaphotrapeziotrapezoid arthrodesis and lunate excision and were followed for a mean of 67 months (range, 49 to 108 mo). The indications for lunate excision included pain and limited motion associated with a collapsed lunate. Clinical evaluation included range of motion, grip strength, and modified Mayo wrist score. Based on plain radiographs, the carpal height ratio, ulnar carpal distance ratio, scaphoid translation ratio, and radioscaphoid angle were measured and any presence of degenerative changes was assessed. To investigate the effects of lunate excision on the radiologic results, we compared 12 patients with stage IIIB Kienböck disease who had only scaphotrapeziotrapezoid arthrodesis as the control group. RESULTS Range of motion tended to be preserved, with a trend toward an increase in extension after surgery. Grip strength and modified Mayo score improved significantly. Fourteen patients with lunate excision demonstrated radiographic ulnar translation of the scaphoid beyond the scapholunate ridge, and radioscaphoid arthritis was observed in 4 patients. Compared to initial postoperative radiographs, the scaphoid translation ratio was significantly decreased, but neither ulnar carpal distance ratio nor radioscaphoid angle showed significant differences. In the control group, neither ulnar translation of the scaphoid nor significant changes of radiologic parameters was found between initial postoperative and final radiographs. CONCLUSIONS Scaphotrapeziotrapezoid arthrodesis with lunate excision for advanced Kienböck disease provided favorable clinical results in terms of pain relief and functional improvement. With the absence of the lunate, however, the scaphoid had a tendency to shift toward the lunate fossa. This study suggests the risk of early development of radioscaphoid arthritis as a negative effect of lunate excision.

Abstract
Thirty-eight patients with advanced Kienböck's disease treated by limited wrist arthrodesis (LWA: n = 10) or radial osteotomy (RO: n = 28) for a fragmented lunate were retrospectively examined after an average of 47.9 and 68.1 months, respectively. Compared with pre-operative values, the active flexion-extension range of motion decreased by about 16.0° in LWA and increased approximately 9.7° in RO and the grip strength improved by approximately 7.5 kg in LWA and 8.0 kg in RO. In both groups, radiographs showed no significant progression of carpal collapse. Although LWA caused some decrease in wrist flexion-extension, both procedures are appropriate for surgical treatment of advanced Kienböck's disease. Most patients experienced a reduction in pain and were able to return to work.

Abstract
PURPOSE Decompression surgery combined with revascularization surgery may provide better results than either alone in the treatment of Kienböck's disease. This study describes our experience with capitate shortening combined with vascularized bone grafting for the treatment of Kienböck's disease in ulnar neutral and ulnar positive variant patients. METHODS Between 1996 and 2004, patients diagnosed with Lichtman stage II or stage IIIA Kienböck's disease with ulnar neutral or ulnar positive wrists were enrolled in this prospective study and had capitate shortening osteotomy with concurrent vascularized bone grafting. Preoperative and postoperative clinical evaluation included wrist arc of motion, grip strength, and overall satisfaction score. Preoperative and postoperative wrist radiographs and preoperative magnetic resonance imaging were performed. Radiographic measurements of preoperative and postoperative ulnar variance and carpal height ratio were also evaluated. The average follow-up period was 41 months (range, 26-65 months). RESULTS Fourteen patients with an average age of 25 years (range, 16-39 years) were studied. The results show significant improvement in grip strength (58% to 78% of the normal side), satisfaction score, and satisfactory arc of motion. The average carpal height ratio was maintained. Average time to osteotomy healing was 48 days. CONCLUSIONS Capitate shortening osteotomy combined with vascularized bone graft is effective in the treatment of ulnar-positive Kienböck's disease prior to the onset of radiocarpal arthrosis.

Abstract
Vascularized bone grafts (VBGs) are techniques in the management of certain types of carpal pathology. VBGs have traditionally been advocated for conditions including delayed and nonunion of fractures and avascular necrosis. The most common indications for VBG have been for scaphoid nonunion, lunatomalacia (Kienböck's disease), and osteonecrosis of the scaphoid (Preiser's disease). Advantages over NVBG have been established. VBGs provide improved blood flow, osteocyte preservation, and accelerated healing rates. Local pedicled VBGs are the most commonly used methods. They are technically less demanding than are free VBGs and are associated with less morbidity. Commonly used donor grafts arise from the dorsal vasculature of the wrist and include the 1,2 intercompartmental supraretinacular artery (1,2 ICSRA), the 2,3 ICSRA, the fourth extensor compartment artery (fourth ECA), and the fifth ECA. A 4 + 5 ECA combination graft has been described to provide a longer pedicle. In managing osteonecrosis, most surgeons would agree that VBG should be reserved for carpal bones with an intact cartilaginous shell and no collapse. In treating scaphoid pathology, indications for VBG include fractures/nonunions with proximal pole avascular necrosis and/or small proximal pole fragments.

Abstract
PURPOSE Advanced Kienböck's disease often involves displaced fractures of the lunate; however, whether such fractures affect surgical outcomes remains unclear. The purpose of this study was to evaluate the results of radial osteotomy for Kienböck's disease with displaced fractures of the lunate and whether these fractures would achieve union. METHODS We reviewed patients who had radial osteotomy for Kienböck's disease between 1975 and 2004. We included only displaced fractures of the lunate that were apparent on lateral radiography, and 31 patients (24 men, 7 women; mean age, 35 y) were then included in this study. Postoperative state of the lunate and clinical results were compared between cases of union and nonunion. RESULTS Preoperatively, mean flexion/extension arc was 76 degrees , and mean grip strength was 22 kg. Postoperatively, mean flexion/extension arc was 84 degrees , and mean grip strength was 30 kg. Radiography revealed fracture healing in 16 wrists. No significant differences between union and nonunion were noted in any assessed clinical items. CONCLUSIONS This study showed approximately 50% union after radial osteotomy. Fracture union did not affect clinical results. Clinical results were good considering the advanced stage of Kienböck's disease. Even with displaced fractures of the lunate, radial osteotomy yields results comparable with other treatments for same-stage patients and thus represents a reasonable approach.

Abstract
Vascularized bone graft procedures have been applied to several maladies of the carpus including proximal pole fractures of the scaphoid, Preiser's disease, and Kienböck's disease. Vascularized bone grafts are capable of primary bony healing without creeping substitution and can thus accelerate fracture healing, replace deficient bone, and revascularize ischemic bone. Long-term data are now available to evaluate the benefits and deficiencies of vascularized grafts in the treatment of many carpal maladies. This article reviews the pertinent literature and provides some treatment algorithms for the use of vascularized bone grafting in cases of carpal pathology.

Abstract
Since its description in 1910, Kienböck's disease has continued to be a difficult problem for clinicians as well as patients. An incomplete understanding of the etiology as well as the natural history of the disease has led to an assortment of surgical treatment options. The authors present a review of Kienböck's disease and the theories behind different surgical interventions, as well as their current approach to treatment of patients with Kienböck's disease.

Abstract
Ulnocarpal impaction syndrome is believed to be caused by abutment between the ulna and the ulnar carpus. We measured radiocarpal and midcarpal ranges of motion in 40 patients with ulnocarpal impaction syndrome by radiographic motion studies. The results showed that the radiocarpal and midcarpal ranges of motion were equally restricted in the affected wrist compared with the unaffected wrist. Therefore, motion of the radiocarpal joint and midcarpal joint contributed equally to total wrist motion bilaterally. No correlation between ulnar variance and the contribution of radiocarpal motion to overall wrist motion was found. Restriction of wrist motion in ulnocarpal impaction syndrome is not caused directly by abutment between the ulna and ulnar carpus, but a satisfactory explanation for restricted motion is still lacking.

Abstract
PURPOSE The use of vascularized bone grafts for the treatment of Kienböck's disease may prevent ongoing lunate collapse and provide relief of wrist symptomatology. This study examines our experience with the use of the 4 + 5 extensor compartmental artery (ECA) bone graft for the treatment of Kienböck's disease. METHODS A retrospective review was performed of all patients having pedicled vascularized bone grafts for Kienböck's disease between 1991 and 2002. Only those patients who had reconstruction with a 4 + 5 ECA graft were included in the study. Presurgical and postsurgical measurements included range of motion, grip strength, and pain evaluation. Measurements of the radiolunate angle, radioscaphoid angle, Stahl's index, and carpal height ratio were taken from presurgical and final follow-up radiographs. Postsurgical magnetic resonance imaging scans were also examined to verify revascularization of the lunate. Statistical analysis was performed using Student's t test. A chi-square test was used to evaluate the effects of lunate revascularization on radiographic progression of disease. Twenty-six 4 + 5 ECA vascularized bone grafts were performed as treatment for Kienböck's disease. The average patient age was 32 years. At the time of surgery 12 patients were graded as stage II, 10 as IIIA, and 4 as IIIB. Mean follow-up time was 31 months. RESULTS At a mean follow-up of 3 months, motion improved from 68% to 71% of the unaffected side, grip strength improved from 50% to 89% of the unaffected side, and 92% of patients had significant improvement in their pain. Satisfactory results were seen in 85% of patients based on the Lichtman outcome score. Seventy-seven percent of patients showed no further collapse on postsurgical radiographs. Sixty-five percent of patients had follow-up magnetic resonance imaging scans at a mean of 20 months after surgery. Seventy-one percent of patients showed evidence of revascularization with improvement in the T2 and/or T1 signal. CONCLUSIONS The 4 + 5 ECA bone graft provides a reliable alternative for the treatment of Kienböck's disease and may aid in lunate revascularization.

Abstract
Seven patients with advanced Kienböck's disease, stage III-B and IV by Lichtman classification, who were treated with lateral closing wedge osteotomy of the distal radius were evaluated clinically and radiographically. The clinical results were correlated with radiographic changes. Five patients had stage III-B and 2 had stage IV disease; average follow-up period was 50 months (range, 24-93 months). Clinical results were good in 4 patients, fair in 2 patients, and poor in 1 patient based on Nakamura's postoperative clinical scoring system. The carpal-ulnar distance ratio and lunate-covering ratio increased and the radioscaphoid angle improved significantly. The improvements in radioscaphoid angle and Nakamura's postoperative clinical score showed a significant correlation. The satisfactory clinical outcome of lateral closing wedge osteotomy of the distal radius for advanced-stage Kienböck's disease can be attributed to the effects of the increased lunate-covering ratio and the improved radioscaphoid angle on carpal alignment.

Abstract
Twelve wrists in 10 patients with a mean age of 23.6 years were treated for symptomatic increased ulnar inclination of the joint surface with corrective osteotomy of the radius. Diagnoses included mild ulnar dysplasia, posttraumatic deformity, Madelung's disease, and multiple hereditary exostosis. All patients had radial-sided wrist pain and an ulnarly displaced arc of radioulnar deviation. Preoperative radiographs showed excessive ulnar inclination of the distal radius, ulnar carpal translation, adaptive carpal malalignment, and frequent distal radioulnar joint incongruency. The patients had decreased pain and improved wrist function at a mean of 5.1 years (range, 2-10 years) after surgery. Average radial deviation changed from 3 degrees to 16 degrees and ulnar deviation from 48 degrees to 29 degrees; flexion/extension and pronosupination remained unchanged. Realignment of the wrist was shown radiographically by a change of ulnar inclination of the radius from 33 degrees to 21 degrees, an increase in scaphoid height from 16.4 to 20.4 mm, and reversal of ulnar carpal translation as shown by an increase in lunate-covering ratio of 64% to 77%. Reduction of the ulnar inclination to normal values by corrective radial osteotomy restores a more physiologic range of motion, decreases symptomatic wrist pain, reverts adaptive carpal changes to normal, increases lunate coverage, and may prevent abnormal cartilage overload in the ulnar compartment of the wrist.

Abstract
The pattern of subchondral bone density has been considered to reflect the stress distribution that occurs under physiologic loading conditions. To determine the force distribution through the wrist joint with Kienböck's disease in living subjects, we applied a computed tomography osteoabsorptiometry and investigated the subchondral bone density pattern across the radio-carpal joint of 6 normal subjects and 10 patients suffering from Kienböck's disease (Lichtman's stage IIIA, 5 patients; stage IIIB, 5 patients). A single density maximum was found in each scaphoid and lunate fossa in all normal subjects. Among the subjects with Kienböck's disease, the current analysis demonstrated that the density maximum area significantly increased in the scaphoid fossa and decreased in the lunate fossa from stage IIIA to IIIB group. These findings indicate that the load is shifted away from the lunate to the scaphoid with the progression of Kienböck's disease in living subjects.

Abstract
Twenty-six patients with Lichtman stages II and III Kienböck's disease had biplane dorsolateral radial closing osteotomy to reduce the radial inclination and dorsal angles on the sagittal plane. The effects of the procedure were studied clinically, radiologically, and by magnetic resonance imaging in a 2- to 6-year follow-up study (average follow-up period, 3.5 years). The signal intensity on T1- and T2-weighted images of the lunate increased after surgery in all patients, suggesting revascularization. The comparative advantages of this technique are discussed with regard to others currently used.

Abstract
This study quantifies the changes in force and pressure distributions across the wrist joint in different stages of Kienböck's disease using a 2-dimensional computer simulation model. Twenty-four cases classified as Lichtman's stage II, IIIA, or IIIB (8 cases in each category) were analyzed using the rigid body spring model technique. A 2-dimensional model in the posteroanterior plane of the wrist was loaded through the metacarpals under a total force of 142 N. The joint forces, peak pressures, and ligament tensions calculated on the involved side were normalized against the contralateral normal side values of the same patient. The results demonstrated that significant changes of the force transmission across the wrist joint occurred only from stage IIIA to IIIB, in which scaphoid rotation was prominent. On the basis of this study, scaphoid rotation plays an important role in affecting the wrist joint contact pressure distribution. This may be responsible for the progression of Kienböck's disease.

Abstract
Arthroscopic examination was performed on 32 wrists of 32 patients with Kienböck's disease to relate the appearance of the intraarticular structures, particularly the articular cartilage, to the radiographic stage. The articular cartilage showed osteoarthritic changes in stage III, although this was not evident on plain radiographs. Cracking in the distal facet and flapping at the proximal facet of the lunate were identified as features of Kienböck's disease. The incidence of interosseous ligament tears was correlated with radiographically determined stage, whereas changes in triangular fibrocartilage were correlated with age and ulnar variance. Wrist arthroscopy is a useful staging tool for Kienböck's disease, supplying helpful information about the intraarticular pathoanatomy which can be used to guide patient management.

Abstract
Eleven consecutive patients, ten men and one woman (median age, 26 years) presenting with Kienböck's disease, were treated with scaphocapitate arthrodesis. Ten patients had grade III, and one had grade II disease by Lichtman classification. The average follow-up period was 36 months (minimum, 1 year). The lunate was left in situ and scaphocapitate arthrodesis was performed with two lag screws and corticocancellous bone graft. The ulnar variance of the affected wrist was negative (-2.23 mm) and significantly different from the unaffected side. Ten patients had complete pain relief and one had persistent pain. Nine returned to their previous vocations.
