Kienbock’S Disease

AbstractIn Kienböck's disease, radius shortening osteotomy is the most common treatment. The Camembert procedure is a wedge osteotomy that shortens only the radius facing the lunate. Its aim is to offload the lunate by redirecting the compression stress of the grip forces toward the scaphoid. The purpose of this study was to determine if the Camembert osteotomy is effective in improving clinical symptoms and limits lunate collapse. The series include 10 patients who underwent a Camembert osteotomy for Kienböck's disease between 2002 and 2012 (one bilaterally). They are six men and four women, aged 40.6 years. Five patients had an additional ulnar shortening osteotomy if ulnar variance was neutral or positive. The mean follow-up is 7 years. Preoperatively, range of motion, grip strength, pain, and functional scores were poor. All osteotomies healed within 3 months. Extension, ulnar deviation, grip, functional scores improved significantly. In 10 cases, there were improvement in the T1 and T2 signals on the magnetic resonance imaging (MRI). There was no lunate collapse. This series shows good results with no worsening of the lunate shape. There was no ulnocarpal impingement. The Camembert osteotomy proposes to offload the lunate and redirect strains toward the scaphoid. The supposed interest is to protect the lunate from collapse. In this small series, the Camembert osteotomy improved function in patients with early stage Kienböck's disease. MRI aspects improve in most cases and no patients collapsed. Camembert can be used in combination with a Sennwald's ulnar shortening when ulnar variance is neutral or positive. Authors propose this procedure for Lichtman's stages 1–2–3A if there are no cartilage or ligament lesions. This is a Level IV, case series study.

We report the short- to medium-term outcomes for patients with Kienböck’s disease and ulnar positive or neutral wrists treated by capitate shortening osteotomy combined with a 4 + 5 extensor compartmental artery vascularized bone graft placed in the lunate. This is a retrospective study of seven consecutive patients with Lichtman Stage 2 to 3B. Radiological and clinical outcomes were evaluated. Six patients maintained their Lichtman stage, one progressed. Mean time to union of the capitate was 10 weeks. Five of six lunates were completely revascularized on MRI scans, with one partial revascularization. Mean follow-up for functional scores was 40 months (range 15 to 62). Mean pain score improved significantly from 7.4/10 preoperatively to 1.9/10 postoperatively, and patient satisfaction was 9.2/10. Mean postoperative Quick Disabilities of Arm, Shoulder and Hand, Patient Evaluation Measure and Patient-Rated Wrist Evaluation scores were improved. All patients returned to their previous work. We conclude that this procedure has good short- to medium-term outcomes. Level of evidence: IV

Abstract Background Salvage procedures, such as proximal row carpectomy, limited or total wrist arthrodesis, and wrist replacement, are generally preferred to treat advanced Kienböck's disease. However, these procedures are particularly aggressive and may have unpredictable results and potentially significant complications. Questions/Purpose This study aimed to present the short- to mid-term clinical and functional results of arthroscopic debridement and arthrolysis in the management of advanced Kienböck's disease. Patients and Methods Fifteen patients in whom Lichtman Stages IIIA to IIIC or IV Kienböck's disease was diagnosed and treated by arthroscopic wrist debridement and arthrolysis were included in this retrospective study. The mean age was 30 years (range: 21–45). The mean follow-up period duration was 36 months (range: 18–60). The Disabilities of the Arm, Shoulder, and Hand (DASH) score, visual analog scale (VAS), wrist range of motion (ROM), and grip strength were measured preoperatively and then again at the final follow-up visit. Results The mean DASH and VAS scores improved from 41 (range: 31–52) and 7.1 (range: 6–8) preoperatively to 13 (range: 8–21) and 2 (range: 0–3; p < 0.001) at the final follow-up visit, respectively. The mean wrist flexion and extension values increased from 32 (range: 20–60 degrees) and 56 degrees (range: 30–70 degrees; p = 0.009) preoperatively to 34 (range: 10–65 degrees; p = 0.218) and 57 degrees (range: 30–70 degrees; p = 0.296) at the final follow-up appointment, respectively, although these findings were statistically insignificant. The mean strength of the hand grip increased from 22.7 (range: 9–33) to 23.3 (range: 10–34; p = 0.372). Conclusion Arthroscopic debridement and arthrolysis may improve wrist function and quality of life due to the preserved ROM and hand grip strength after short- to mid-term follow-up periods despite the radiographic progression of Kienböck's disease. Level of Evidence This is a Level IV, retrospective case series study.

Introduction Isolated ulnar shortening osteotomies can be used to treat ulnocarpal abutment secondary to radial shortening following distal radius fractures. Given the increase of fragility distal radius fractures awareness of treating the sequelae of distal radius fractures is important. We present the largest reported case series in the UK of ulnar shortening osteotomies for this indication. Materials and methods Twenty patients with previous distal radial fractures were included, who presented with wrist pain and radiologically evident positive ulnar variance secondary to malunion of the distal radius with no significant intercalated instability. Patients were treated with a short oblique ulnar shortening osteotomy, using a Stanley jig and small AO compression plate system. Pre- and postoperative radiographical measurements of inclination, dorsal/volar angulation and ulnar variance were made. Patients were scored pre- and postoperatively using the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and Patient-Rated Wrist Evaluation scores by two orthopaedic surgeons. Mean follow-up was 24 months after surgery. Results Radiographical analysis revealed a change in the ulnar variance with an average reduction of 5.74 mm. Mean preoperative scores were 61.1 (range 25–95.5) for QuickDASH and 70.4 (range 33–92) for Patient-Rated Wrist Evaluation. At the latest follow-up, mean postoperative QuickDASH scores were 10.6 (range 0–43.2) and 17.2 (range 0–44) for Patient-Rated Wrist Evaluation. Differences in scores after surgery for both QuickDASH and Patient-Rated Wrist Evaluation were statistically significant (P < 0.01). Conclusions The ulnar shortening osteotomy is a relatively simple procedure compared with corrective radial osteotomy, with a lower complication profile. In our series, patients showed significant improvement in pain and function by correcting the ulnar variance thus preventing ulna–carpal impaction.

The aim of this study was to determine the incidence of asymptomatic Kienböck’s disease in patients who attended the Dr George Mukhari Hospital (formerly Ga-Rankuwa Hospital), as well as the relevance of ulnar variance on the disease. This was a retrospective study. In a 12 month period we reviewed postero-anterior radiographs of 1287 patients seen at our radiology department, with complaints unrelated to the upper limb including the wrist and hand. We identified 23 cases (1.9%) of asymptomatic Lichtman stage II–IV Kienböck’s disease in our African population. The majority (63%) were male with an average age of 49 years, and 37% were female with an average age of 46.5 years. All cases were unilateral and all were in the dominant hand. Thirteen cases (57%) had an ulnar neutral wrist and the remaining ten (43%) had an ulnar negative variance. The vast majority (83%) were unemployed. Analysis of the data shed no further light on the aetiology. The relevance of ulnar variance as an aetiological factor is questioned.

Forty four patients with forty seven wrists suffering from Kienböck’s disease were re-examined. The mean observation time was 20.5 years. In all forty seven wrists the treatment had been immobilization. Using a standard X-ray projection, and a reliable method of ulnar variance measuring, the ulnar variance was determined by three observers independently. Comparing the result with the ulnar variance in normal wrists we found the so-called “ulnar minus variant” overrepresented in patients with Kienböck’s disease. However, comparing X-rays taken at the time of diagnosis with X-rays at re-examination, we found in eight out of forty seven wrists that a subchondral bone formation in the distal radius opposite the lunate bone had taken place. This bone formation will tend to enhance the negative value of ulnar variance measurements, and suggests an explanation of the overrepresentation of “ulnar minus variants” in Kienböck’s disease. Excluding these eight wrists from the material and comparing the mean ulnar variance value in the remaining thirty nine wrists with the mean value in normal wrists no statistical difference was shown. Based on these observations it seems unlikely that the “ulnar minus variant” has any bearing on the cause of Kienböck’s disease.
