Prospective Cohort Study Comparing Ligament Reconstruction with Tendon Interposition and Suture-Only Suspension Arthroplasty.

BACKGROUND: Basal joint arthritis is a common form of osteoarthritis. There is no consensus procedure for maintenance of trapezial height following trapeziectomy. Suture-only suspension arthroplasty (SSA) is a simple method for stabilizing the thumb metacarpal following trapeziectomy. METHODS: This single-institution, prospective, cohort study compares trapeziectomy followed by either ligament reconstruction with tendon interposition (LRTI) or SSA for the treatment of basal joint arthritis. Patients underwent LRTI or SSA from May of 2018 to December of 2019. Visual analogue scale pain scores; Disabilities of the Arm, Shoulder and Hand questionnaire functional scores; clinical thumb range of motion, pinch, and grip strength data; and patient-reported outcomes were recorded and analyzed preoperatively and at 6 weeks and 6 months postoperatively. RESULTS: Total number of study participants was 45 (LRTI, n = 26; SSA, n = 19). Mean ± SE age was 62.4 ± 1.5 years; 71% were female patients; and 51% underwent surgery on the dominant side. Visual analogue scale scores improved for LRTI and SSA ( P < 0.0001) over 6 months, with no differences between groups at any time point ( P > 0.3). Disabilities of the Arm, Shoulder and Hand questionnaire scores improved for LRTI and SSA over 6 months ( P < 0.0001), with no differences between groups at any time point ( P > 0.3). Following SSA, opposition improved ( P = 0.02), but not as well for LRTI ( P = 0.16). Grip and pinch strength decreased following LRTI and SSA at 6 weeks but recovered similarly for both groups over 6 months. Patient-reported outcomes were generally no different between groups at all time points. CONCLUSION: LRTI and SSA are similar procedures following trapeziectomy relative to pain, function, and strength recovery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Pyoderma Gangrenosum Following Carpal Tunnel Release: A Case Report.

CASE: A 51-year-old woman with diabetes developed wound complications consistent with presumed infection 5 days after undergoing a carpal tunnel release. Despite multiple debridements, the wounds continued to necrose and deteriorate. A diagnosis of pyoderma gangrenosum eventually was made, and the condition improved with the administration of systemic corticosteroids. CONCLUSION: Pyoderma gangrenosum, a form of neutrophilic dermatosis that rarely occurs as a complication of surgery, resembles a postoperative infection. Astute awareness of the condition can prevent a delayed diagnosis and unnecessary surgical procedures.

Unstable dorsal proximal interphalangeal joint fracture-dislocations treated with extension-block pinning.

Unstable proximal interphalangeal (PIP) joint fracture-dislocations, which can cause significant disability, can be treated with multiple techniques. Extension-block pinning (EBP) allows for early motion and is less technically demanding than alternative surgical treatments. In the study reported here, 12 patients with unstable dorsal PIP fracture-dislocations were treated with closed reduction of the PIP joint followed by percutaneous insertion of a Kirschner wire (K-wire) into the distal aspect of the proximal phalanx. For these patients, extent of articular surface involvement averaged 43% (range, 25%-75%). Active motion was initiated early after surgery, and the K-wire was removed a mean of 25 days after pinning. Radiographic reduction of joint dislocation was achieved and maintained for 11 of the 12 patients at a mean follow-up of 35.5 months. At follow-up, mean visual analog scale (VAS) score was 0.64 (scale, 0-10). Mean score on the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire was 5.7, suggesting minimal functional impairment. Mean PIP active motion was 84° (range, 50°-110°). Grip strength was equal between operative and contralateral hands. Patient satisfaction most closely correlated with low VAS and QuickDASH scores. One patient developed a malunion, which was treated with corrective osteotomy. EBP is a simple, safe, and reproducible technique for unstable PIP fracture-dislocations. This technique yields outcomes similar to those reported for more complex surgical procedures.

Joint space height correlates with arthroscopic grading of wrist arthritis.

BACKGROUND: Osteoarthritis of the radiocarpal joints is commonly encountered by hand surgeons. To date, there is no well-defined method of radiographically grading osteoarthritis of the wrist. METHODS: Preoperative radiographs of 48 patients undergoing wrist arthroscopy were evaluated retrospectively. Images were graded subjectively by five surgeons based on overall severity of arthritis, osteophytes, subchondral cysts, and subchondral sclerosis. The joint space height (JSH) ratio was calculated by measuring the space of the mid-radioscaphoid and mid-radiolunate joints and dividing each by the height of the capitate. Arthroscopic grading of arthritis was obtained from operative records and compared to subjective and objective grades. ANOVA testing evaluated for statistical significance with p < 0.05. Inter-rater and intra-rater reliability was determined using Pearson's correlation analysis and Cohen's kappa coefficient. RESULTS: Objective measurement using the JSH ratio demonstrated a significant decrease as arthroscopic arthritis grade increased for both radioscaphoid and radiolunate joints. Subjective grading of radioscaphoid and radiolunate joints was able to detect moderate/severe, but not mild arthritis. Subjective grading underestimated the degree of arthritis, particularly in the radiolunate joint. Inter-rater reliability was better for objective compared to subjective grading. CONCLUSIONS: Subjective grading of wrist arthritis can detect moderate/severe radiocarpal arthritis but poorly evaluates early arthritis and underestimates severity. Objective grading using the JSH ratio accurately grades radioscaphoid arthritis and detects early radiolunate arthritis. The JSH ratio more accurately assesses radiocarpal arthritis compared with subjective grading. As there currently is no accepted method to radiographically grade wrist arthritis, the JSH ratio represents a promising option.

Technical aspects of the recipient operation in hand transplantation.

The goal of hand allotransplantation is to achieve graft survival and useful long-term function. To achieve these goals, precise surgical technique is of critical importance. The key surgical steps and sequence of events in hand allotransplantation are similar to major upper extremity replantations, but are modified to accommodate major conceptual differences that exist between the two procedures.

Outcome of surgery for lateral epicondylitis (tennis elbow): effect of worker's compensation.

We retrospectively compared the results of extensor origin release for lateral epicondylitis (tennis elbow) against worker's compensation (WC) status. All patients (N = 57) underwent extensor origin release between October 1989 and June 1998. For the 33 patients (37 elbows) who received WC, mean follow-up was 55 months; for the 25 patients (26 elbows) who did not receive WC, mean follow-up was 45 months. Pain relief, symptom recurrence, satisfaction with procedure outcome, and ability to return to work (same or similar job) were evaluated. Pain relief was reliably achieved in the WC and non-WC groups (36/37 and 24/26 elbows, respectively). Symptom recurrence was intermittent in both groups, and few patients sought medical intervention for recurrent symptoms. Patient satisfaction was high in the WC and non-WC groups (35/37 and 26/26 elbows, respectively). A majority of patients in both groups returned to work, but a significantly higher percentage of patients in the WC group changed jobs because of persistent symptoms.
