Skin grafting prevents recurrence in Dupuytren's disease and extension correlates with fibrosis diathesis score.

Full thickness grafting can be considered after fasciectomy for Dupuytren contracture in severe cases with skin shortage or in radical dermofasciectomy. It is a common dogma that these skin grafts may prevent disease recurrence. We reviewed 47 patients after fasciectomy and full-thickness skin grafting for Dupuytren contracture at 3-16 years' follow-up. Recurrence beneath the skin graft and extension of the disease in the rest of the hand were recorded. Age at onset, gender and factors considered to influence the outcome due to fibrosis diathesis, such as bilateral disease, family history and ectopic lesions, were noted. The Tubiana classification was used to grade disease severity at surgery and at follow-up. None of the patients manifested recurrence underneath the skin graft, but the disease did show extension in 83% of cases. Disease extension was more likely in patients with higher fibrosis diathesis scores. We conclude that skin grafting may prevent disease recurrence underneath the grafts, but extension of the disease correlates with fibrosis diathesis. LEVEL OF EVIDENCE: IV, therapeutic cohort study.

Long-term follow-up of the three-ligament tenodesis for scapholunate ligament lesions: 9-year results.

We report on a retrospective cohort of 50 cases of three-ligament tenodesis for scapholunate instability. Fifteen cases (30% of our cohort) needed salvage surgery (11 proximal row carpectomies, 2 partial and 2 total wrist fusions) at an average of 33 months and are considered "failures". Of the 35 remaining cases ("success"), 16 (32% of our cohort) were reviewed at average 111 months and had good functional outcomes (QuickDASH 18/100, PRWE 11/100, pain 1/10, satisfaction 9/10). Return to work was 81% and grip strength was 80% of the opposite side. Radiological review found no significant correction in the short-term: scapholunate angle (SLA) from 72° to 69° (p = 0.544), scapholunate distance (SLD) from 3.4 mm to 3.4 mm (p = 0.833) and radiolunate angle (RLA) from 17° to 13° (p = 0.253). A significant deterioration in SLA from 72° to 80° (p = 0.014), not correlated to function, was seen at final follow-up. Radiographic progression to wrist degeneration was seen in 63% of successful cases. In failed cases, we noticed inferior radiographic parameters in the short-term: SLD of 4.6 mm in failed versus 3.4 mm in successful cases (p = 0.038) and RLA of 22° in failed versus 13° in successful cases (p = 0.046). Complication rate was 10% (2 scaphoid necroses, 1 septic arthritis and 2 complex regional pain syndromes). Despite radiological deterioration of SLA and development of degeneration in most cases, three-ligament tenodesis can give satisfactory wrist function in some patients, but we observed a significant number of failures and a high complication rate. LEVEL OF EVIDENCE: IV.

Lateral elbow tendinopathy: surgery versus extracorporeal shock wave therapy.

Lateral elbow pain caused by tendinopathy - tendinosis - or tennis elbow is a highly prevalent problem. Unfortunately, no treatment method can guarantee clinical success. Inspired by the lithotripsy technique used for kidney stones, extracorporeal shock wave therapy (ESWT) has been introduced as an alternative to surgical treatment 25 years ago. In a randomized prospective study, we compared 15 patients with lateral elbow tendinopathy who were operated and 14 who underwent ESWT. Almost all patients had good or excellent outcomes according to the criteria by Verhaar. Subjective improvement was 57% for the ESWT group and 76% for the surgery group. No significant differences between both groups were found (p = 0.07). We therefore recommend considering non-invasive techniques such as ESWT treatment prior to surgery in tennis elbow.

Eaton and Littler Ligament Reconstruction for the Painful first Carpometacarpal Joint : Patient satisfaction.

The ligamentous reconstruction according to Eaton and Littler (7) was designed to restore the stability of the carpometacarpal joint of the thumb. We evaluated the patients' satisfaction after an Eaton and Littler-procedure as well as possible risk factors in the development of thumb basal joint instability. A retrospective chart review and clinical assessment or telephone survey are executed in 33 patients, with a mean follow-up of 7 years. Only 45% of the patients were satisfied. Within the group of clinical assessed patients, there were significant differences in thumb function comparing operated with not operated side. Overall joint hypermobility can be a contributing factor for this thumb basal joint instability, but has no effect on the outcome after an Eaton-Littler procedure.

Evaluation of the metaphyseal ulnar shortening technique according to Sennwald.

The outcome of a metaphyseal ulnar shortening osteotomy, reported by Sennwald as an alternative option for ulnar abutment syndrome, was evaluated with -regard to the functional results, pain relief and incidence of complications. METHOD: We conducted a review of 12 patients ; measured parameters were DASH score, PRWE, VAS for pain, grip force and wrist motion. RESULTS: Only disability improved significantly with a DASH score of 42 (p = 0.03). The function and pain assessment scores did not improve in 3 patients. We found no correlation between change in functional scores and other measured variables. Six patients were reoperated for prominent screw heads or new-onset distal radioulnar joint osteoarthritis. CONCLUSION: All osteomies healed fast and uneventfully and disability improved in most patients but 25% did not improve and 50% were re-operated. Further investigation is needed to evaluate the value of the metaphyseal osteotomy as an alternative treatment for ulnar abutment syndrome.

Avascular necrosis of the capitate: report of six cases and review of the literature.

Avascular necrosis of the capitate is rare. Little is known about the aetiology, disease progression or optimal management. From 1992 to 2012 we treated six patients; four had a scaphocapitolunate arthrodesis and two had a four corner arthrodesis. The average follow up was 9 years (range 1-20). Three patients had good or excellent results, two fair and one poor, based on a visual analogue scale for pain and satisfaction and a Quick-DASH score. The Mayo wrist score was satisfactory in five cases and poor in one. Better results were seen when the arthrodesis fused. In the English, French and German literature 42 other cases were found. The aetiology, patient characteristics, clinical presentation, treatment and outcome were reviewed.

Giant cell tumor of distal phalanx in an adolescent with Goltz-Gorlin syndrome.

We report on a unique case of a young female patient with the Goltz-Gorlin syndrome who developed a giant cell tumor of bone in the distal phalanx of the thumb. This case is noteworthy because of the combination of some unusual features. Firstly, it is only the fifth case report on the association of giant cell tumor of bone and the Goltz-Gorlin syndrome. Also the localization of the lesion in the bones of the hand and the presentation at adolescent age is rarely seen.

Poland's syndrome with radial aplasia of the hand.

A case of symbrachydactyly with ipsilateral radial club hand is reported. Although this can fit in the vascular dysruption sequence, this is a rare combination.

Optimization of drug delivery systems for intraperitoneal therapy to extend the residence time of the chemotherapeutic agent.

Intraperitoneal (IP) chemotherapy is an effective way of treating peritoneal carcinomatosis of colorectal origin after complete cytoreduction. Although IP therapy has been already performed for many years, no standardized treatment design has been developed in terms of schedule, residence time, drug, or carrier solution. Because of the fast clearance of the conventional intravenous (IV) drug delivery systems used for IP therapy, a lot of research is performed to optimize IP drug delivery and extend the residence time of the cytotoxic agent in the peritoneal cavity. This paper reviews the recent advances made in drug delivery systems for IP chemotherapy, discussing the use of microparticles, nanoparticles, liposomes, micelles, implants, and injectable depots for IP delivery.

Long term outcome of trapeziectomy with ligament reconstruction/tendon interposition versus thumb basal joint prosthesis.

Several surgical techniques to treat thumb basal joint arthritis have been described. In this study we compared the results of a cemented thumb basal joint with trapeziectomy with a ligament reconstruction and tendon interposition. A questionnaire was sent to all 519 patients, 322 (with 382 procedures) responded. No significant differences were found when comparing impairment, pain, patient satisfaction and disability. Given the fact that the superiority of a prosthesis cannot be proven and the cost of the implant is greater, we recommend the trapeziectomy with ligament reconstruction and tendon interposition as opposed to arthroplasty as the first choice in the treatment of basal joint osteoarthritis of the thumb.

Prospective study to assess fluid accumulation and tenosynovial changes in the aromatase inhibitor-induced musculoskeletal syndrome: 2-year follow-up data.

BACKGROUND: Aromatase inhibitors (AIs) frequently lead to the AI-induced musculoskeletal syndrome (AIMSS). Looking into its pathophysiology, 6 months of AI therapy thickens the tendon sheath with intra-articular fluid (IAF) retention and loss of grip strength. We here report 24-month follow-up data. PATIENTS AND METHODS: A prospective cohort study of 33 postmenopausal breast cancer patients received adjuvant endocrine therapy; 27 received an AI and 6 received tamoxifen. At baseline, 6 and 24 months patients had a rheumatologic examination, including a grip strength test, and magnetic resonance imaging of both hands and wrists. The primary end point was tenosynovial changes; secondary end points were changes in morning stiffness, grip strength and IAF. RESULTS: Twenty-three AI and 5 tamoxifen patients completed all investigations. Between month 6 and 24, IAF further increased in AI users (P = 0.04) but not in tamoxifen users, and grip strength further decreased in both groups. The worsened tenosynovial changes were strongly correlated with a decrease in grip strength. At 24 months, morning stiffness continued to be present in over a third of AI users. CONCLUSION: AIMSS represents a substantial problem in breast cancer patients. It is associated with tenosynovial changes, IAF retention, joint stiffness and loss of grip strength that do not improve with prolonged use.

Focal fibrocartilaginous dysplasia in the upper limb: case report and review of the literature.

Focal fibrocartilaginous dysplasia (FFCD) is an uncommon, benign bone lesion that causes angular deformities of the long bones in young children. Most deformities were seen around the knee. Diagnostic criteria are based on clinical and radiological signs: unilateral angular deformity in a long bone of a young child, associated with on X-ray a typical lucent bony defect with surrounding sclerosis at the concavity of the deformity with a cortical defect. The etiology is not understood. There were 16 cases described previously involving the upper extremity: 9 cases with FFCD of the ulna, 3 of the humerus, 2 of the radius and 2 of the phalanx. We report a case of cubitus varus deformity in a young girl of 2 years and 2 months where the deformity worsened very quickly. We believe that debridement of the fibrous tether at very young age will prevent further deformity and can correct spontaneously by remaining growth.

Aromatase inhibitor-induced loss of grip strength is body mass index dependent: hypothesis-generating findings for its pathogenesis.

BACKGROUND: Our preliminary results showed that tenosynovial changes and decrease in grip strength are associated with the aromatase inhibitor-induced musculoskeletal syndrome (AIMSS). Here, we report the final results and assess the relationship between grip strength and body mass index (BMI). PATIENTS AND METHODS: We conducted a prospective study including postmenopausal early breast cancer patients receiving either an aromatase inhibitor (AI) or tamoxifen. Primary end point was change from baseline in tenosynovial abnormalities. Secondary end points were changes from baseline in morning stiffness, intra-articular fluid and grip strength and its association with BMI. RESULTS: After 6 months of therapy, 74% [95% confidence interval (CI) 51% to 89%] of AI-treated patients had worsened tenosynovial abnormalities, 56% (95% CI 34% to 75%) had increased intra-articular fluid, and 22% (95% CI 9% to 45%) had increased morning stiffness. Grip strength decreased 8% for the left hand (95% CI 2% to 21%) and 11% for the right (95% CI 4% to 17%). Regression analysis suggested that grip strength decreased more for subjects with high or with low BMI. CONCLUSIONS: AIMSS is characterized by tenosynovial changes, intra-articular fluid and morning stiffness. We hypothesize that the quadratic association between BMI and loss of grip strength reflects AI-induced changes on the endocrine control of the growth hormone insulin-like growth factor-I pathway.

Reliability and reproducibility of Kienbock's disease staging.

We evaluated the interobserver reliability and intraobserver reproducibility of the Lichtman et al. classification for Kienböck's disease by getting four observers with different experience to look at 70 sets of wrist radiographs at different points in time. These observers staged each set of radiographs. Paired comparisons of the observations identified an agreement in 63% of cases and a mean weighted kappa coefficient of 0.64 confirming interobserver reliability. The stage of the involved lunate was reproduced in 78% of the observations with a mean weighted kappa coefficient of 0.81 showing intraobserver reproducibility. This classification for Kienböck's disease has good reliability and reproducibility.

Dupuytren's disease: a predominant reason for elective finger amputation in adults.

Dupuytren's disease (DD) can lead to severe disabling finger contractures resistant to surgical treatment. In some cases, finger or ray amputation is considered, due to a severe functional deficit or vascular injury. To evaluate the weight of amputation surgery in DD, a retrospective study was conducted over a 5-year time interval, outlining all indications for elective finger amputation and its prevalence in the total of surgical interventions for DD. The outcome in DD was compared to post-traumatic amputations. Out of 31 elective finger and ray amputations, 12 (39%) were indicated for DD, all in the 4th or 5th ray, of which 92% were in recurrent disease. In the 646 surgical procedures for DD in the matching time interval, we conclude that almost 2% were elective amputations. The outcome of amputation in DD was similar to post-traumatic amputations. Based on these data, we feel that patients should be informed that sometimes, surgical treatment for Dupuytren's disease can lead to an eventual decision to amputate.

Lipofibromatous hamartoma of the median nerve and macrodactyly.

A case of lipofibromatous hamartoma of the median nerve with macrodactyly of 2 digits is described. Nerve stripping resulted in a growth control.

Proximal row carpectomy with or without postoperative immobilisation.

Previously published reports have shown good results after proximal row carpectomy in all cases that had a postoperative immobilisation period from 1 to 4 weeks. Immobilisation is thought to be necessary because of the risk of postoperative subluxation of the carpus and for pain relief. There is, however, no evidence of its value. The results in 13 patients who underwent proximal row carpectomy without postoperative immobilisation were compared with those in 25 patients who underwent proximal row carpectomy with postoperative immobilisation for 4 weeks. After a mean follow-up period of 27 months, no significant differences were found for pain, range of motion or return to work between the two groups. We conclude that postoperative immobilisation is not necessary after proximal row carpectomy.

Factors influencing return to work after surgical treatment for carpal tunnel syndrome.

BACKGROUND: Controversy exists regarding the factors influencing the duration of work incapacity after surgically treated carpal tunnel syndrome (CTS). AIM: To determine relevant factors related to return to work. METHODS: Surgical technique, clinical factors, demographic factors, other medical problems, psychosocial factors, work-related and economical factors were reviewed in patients operated on for CTS. Statistical multivariate analyses were performed to identify the baseline factors influencing the work incapacity period. RESULTS: A total of 107 cases were reviewed. Professional exposure to repetitive movements and heavy manual handling activity were associated with a longer return-to-work interval. The duration of work incapacity period was not significantly related to the socioprofessional category of the patient (self-employed or employee) or to the type of the procedure (open versus endoscopic surgery). CONCLUSION: Work-related features have a more important influence on return to work than personal, pathological or surgical features.
