A Meta-Analysis of the Outcomes of Ligament Reconstruction Compared to No Reconstruction with or without Tendon Interposition Following Trapeziectomy for Thumb Carpometacarpal Joint Osteoarthritis.

Background: The outcomes of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) compared to the trapeziectomy (T) alone or in combination with tendon interposition (TIA) in the treatment of osteoarthritis (OA) of the carpometacarpal joint (CMCJ) of the thumb are still debated. The aim of this study is to conduct a meta-analysis to determine whether the outcomes of LRTI were better compared to T or TIA. Methods: A meta-analysis of randomised trials that included the outcomes of patients with thumb CMCJ OA that underwent LRTI, T or TIA with at least 1 year follow-up. The outcomes included number of patients with pain 1 year after surgery (NPP), Visual Analog Scale for Pain (VAS Pain), key pinch strength, patient reported outcome measurements (PROMs) and number of adverse effect (AEs). The effect was assessed using mean difference for quantitative variables (VAS pain and key pinch), standardised mean difference for PROMs and relative risk for binary variables (NPP and AEs). Results: Seven studies met the inclusion criteria (857 participants: 438 LRTI vs 419 T/TIA). We did not find significant differences between LRTI and T/TIA in NPP, VAS pain, key pinch at 1 year and 5 years or more, PROMs, and AEs at 1 year and at 5 years or more after surgery. Conclusions: The outcomes of LRTI are not superior to T or TIA in the treatment of OA of the thumb CMCJ. Level of Evidence: Level I (Therapeutic).

Ligaments and muscles stabilizing the radio-ulno-carpal joint.

The technical simplicity of the Darrach procedure may explain why it has been so popular. Excising the distal ulna, however, may have potentially undesired consequences to the biomechanics in two areas: the distal radioulnar and the ulno-carpal joints. These conjointly define the radio-ulno-carpal joint (RUCJ). The RUCJ is not a small and irrelevant articulation that can be removed without possibly paying a functional penalty. It is an important link of the antebrachial frame that provides stability to the distal forearm and the carpus. This article revisits the mechanisms by which some ligaments and muscles ensure that all forces about and within the RUCJ are dealt with efficiently.

Prospective Clinical Trial Comparing Trapezial Denervation With Trapeziectomy for the Surgical Treatment of Arthritis at the Base of the Thumb.

BACKGROUND: Trapeziectomy is considered to be the "gold standard" procedure for first carpometacarpal joint (first CMCJ) osteoarthritis. First CMCJ denervation offers the potential benefit of a shorter procedure with bone and joint preservation and swift postoperative rehabilitation. This trial aimed to compare functional outcomes, patient satisfaction, quality of life, and cost effectiveness following these treatments. METHODS: This study was a prospective clinical trial commencing December 2005 to November 2013. A range of functional outcomes assessments were used preoperatively at 6 and 12 mo and 5 y after surgery. These included measurements of strength/motion, visual analogue score, Michigan Hand Outcomes and the European Quality of Life-5 Dimensions questionnaires. Data were analyzed using a two-sample t-test and Mann-Whitney test. RESULTS: A total of 45 patients were studied of 55 recruited. Age ranged from 41 to 72 (mean = 59). Thirty-five patients underwent denervation and 10 initially had trapeziectomy. Nine patients were converted to trapeziectomy within an average of 6 to 12 mo. There was no significant difference in the functional outcomes at different points of follow-ups. Similarly, there was no significant difference in the time of return to work or cost effectiveness. Denervation achieved a success rate of just above 70%, whereas no revisions were required for the trapeziectomy group. CONCLUSIONS: There was no difference between the two treatments. First CMCJ denervation does not appear to be superior to trapeziectomy. However, the advantage of rapid rehabilitation makes it more favored by patients but at the expense of 30% reoperation rate. LEVEL OF EVIDENCE: Level II.

Trapezoid fractures: report of 11 cases.

PURPOSE: Trapezoid fractures are rare. Mostly single cases reports appear in the literature. The purpose of this study was to review 11 patients treated for trapezoid fractures at our center. METHODS: We reviewed all trapezoid fractures that presented over the past 10 years at our institution. We reviewed case notes regarding mechanism of injury, fracture pattern, mode of diagnosis, and time to diagnosis and treatment. RESULTS: We treated 11 patients for trapezoid fractures over the 10-year period. A correct diagnosis was made in 5 cases on initial evaluation. Most trapezoid fractures were diagnosed on computed tomographic scan. The fracture plane was predominantly sagittal. Coronal fractures could not be diagnosed on plain radiographs. CONCLUSIONS: Fractures of the trapezoid should be suspected from the mechanism of injury, in particular, axial force, and from local tenderness. These fractures may be underdiagnosed. We recommend computed tomography rather than plain radiography alone in case of clinical suspicion. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic IV.

Treatment of a little finger synovial cyst by repair of an opening in the wrist capsule: case report.

As synovial fluid from the wrist may leak into the ulnar bursa and from there into the flexor synovial sheath in the little finger, the origin of a synovial cyst of the pulp of the little finger may be in the wrist. Here we present the surgical treatment of a patient with a synovial cyst of the pulp of the little finger by surgery of the wrist and palm of the hand after failed conservative treatment.

An aberrant branch of the radial digital nerve in the index finger: case report.

This report describes an incidental finding of an aberrant branch of the radial digital nerve in the index finger of a 39-year-old woman who cut herself with a knife.

Trends in elective hand surgery referrals from primary care.

INTRODUCTION: Two prospective audits of activity in a hand unit were performed, in 1989-1990 and during 2000-2001, to identify trends in elective hand surgery referrals from primary care. PATIENTS AND METHODS: Two 6-month prospective audits of activity in a hand unit were performed, including elective referrals from primary care. Data were collected on all in-district referrals with elective hand disorders. Cross boundary flow was identified to permit assessment of changes in referrals by diagnosis over a decade. RESULTS: There was a 36% increase in health authority referrals for elective hand surgery over the decade (from 289 to 392 per 100,000 of population per year). The number of elective hand surgery operations rose 34% over the decade (from 149 to 199 operations per 100,000 of population per year). Carpal tunnel syndrome (the commonest reason for elective referral) almost doubled (from 59.7 to 112 per 100,000 of population per year). Referrals for ganglion, the second most common elective referral, rose modestly. Referrals for osteoarthritis (commonly basal thumb arthritis) almost trebled over the decade to become the fourth commonest condition referred to the hand unit (from 12.7 to 34 per 100,000 of population per year). Referrals for Dupuytrens disease, trigger finger and rheumatoid arthritis were relatively unchanged over the decade. Congenital hand referrals are uncommon but doubled during the decade. CONCLUSIONS: Hand surgery referrals rose by 36% over the decade. Analysis of the commoner conditions referred reveal a high prevalence within the community with the possibility of increased referrals in years to come.
