Consolidation rate in ulnar shortening osteotomy with the APTUS Wrist plate.

INTRODUCTION: Ulnocarpal impaction syndrome causes pain on the ulnar side of the wrist. Various surgical techniques have been described. Ulnar shortening osteotomy is now a standard treatment. However, it is associated with complications such as non-union of the osteotomy site. The main study objective was to report the rate of radiographic consolidation after ulnar shortening osteotomy with a cutting guide. MATERIAL AND METHODS: This multicenter retrospective study of 30 cases reported clinical and radiographic criteria at a minimum 6 month's follow-up. RESULTS: The non-union rate was 3.4%. One case presented non-union of the osteotomy site. 87% of patients were satisfied or very satisfied with the procedure. Mean VAS pain rating was 2.7 ± 2.4. Mean QuickDASH and PRWE scores were 24.7 ± 19.2 and 28.6 ± 25. Mean strength on Jamar dynamometer was 27.4 ± 8.9 kg. One patient developed complex regional pain syndrome. Five patients required plate removal for hardware-related discomfort. DISCUSSION: Ulna shortening osteotomy with the Aptus Wrist plate provides a standardized approach to the surgical treatment of ulnocarpal impaction syndrome. Compared with other series in the literature, the procedure provided satisfactory consolidation and clinical results.

Long-term outcomes of trapeziectomy with Gore-Tex® ligament reconstruction for trapezio-metacarpal osteoarthritis.

BACKGROUND: Trapezio-metacarpal osteoarthritis is a common condition for which the reference standard treatment after failure of non-operative measures is trapeziectomy. Several techniques have been devised to avoid proximal migration of the first metacarpal bone (M1) with impingement on the scaphoid bone. We have developed a Gore-Tex® ligament reconstruction technique that avoids potential complications of tendon harvesting. The objective of this study was to assess the long-term outcomes of this technique. HYPOTHESIS: Trapeziectomy with Gore-Tex® ligament reconstruction is a reliable option for providing lasting pain relief in patients with trapezio-metacarpal osteoarthritis. MATERIALS AND METHODS: We conducted an observational, single-centre, single-surgeon, retrospective cohort study in consecutive patients managed by primary trapeziectomy. We excluded patients with revision trapeziectomy or less than 10 years' follow-up. The primary outcome was event-free survival, defined as absence of revision surgery and of a numerical rating scale score for pain above 3/10. The secondary criteria were clinical tolerance of the Gore-Tex® implant and radiological changes. The patients were assessed at last follow-up either in person or during a teleconsultation. RESULTS: Of 78 included joints, 64 were assessed during patient visits and 24 by teleconsultation. At 10 years, the event-free survival rate was 91.3%, and 60.3% of patients were free of pain. Evidence of osteolysis was visible in 24% of patients. No patient experienced clinical intolerance of the Gore-Tex® implant. The mean Disabilities of Arm, Shoulder and Hand score was 25.5. Metacarpo-phalangeal hyperextension was significantly increased, to 30.6°, and the mean trapezial space ratio was significantly decreased, to 39.1% of the baseline value. CONCLUSION: Long-term event-free survival was high. Functional outcomes and pain were similar to previous reports. Trapeziectomy with Gore-Tex® ligament reconstruction obviates the need for tendon harvesting. Osteolysis developed in some patients but did not correlate with clinical intolerance. Long-term clinical and radiological monitoring is in order after Gore-Tex® implantation. LEVEL OF EVIDENCE: IV, Observational, single-centre, single-surgeon, retrospective cohort study.

Terrible triad injury of the elbow: a historical perspective.

PURPOSE: The aims of this study are to summarize (1) the history of terrible triad injury (TTi) treatment and (2) the clinical and biomechanical data that engendered its evolution. METHODS: A literature search was performed using five electronic databases. Results were discussed as a chronologic review of the relevant literature between 1920 and 2022. RESULTS: In 1962, Osborne was the first to describe a link between elbow dislocation, radial head fracture, and lateral collateral ligament complex injury via a novel mechanism: posterolateral rotatory instability (PLRI). Given that untreated elbow instability leads to post-traumatic osteoarthritis (PTOA), there has been increasing interest in elbow biomechanics since the 1980s. Data from studies in that period revolutionized the approach to elbow instability. The authors demonstrated that TTi could occur via a PLRI mechanism with a disruption of the lateral collateral ulnar ligament and a functionally competent anterior medial collateral ligament (aMCL). Since the 1990s, due to the difficulty in identifying its pathoanatomic features, some began to speculate about a sequence of injuries and mechanisms leading to TTi. However, the clinical literature has largely been unable to reproduce in vitro findings describing the pathomechanics of TTi. Some aspects of treatment remain controversial including systematic coronoid and aMCL repair. CONCLUSION: Despite a growing body of biomechanics data, there is no widely accepted surgical protocol for the treatment of TTi. Functional outcomes among patients have greatly improved. Better diagnosis and treatment of infra-clinical instability after a TTi may be an important stepping stone to prevent the onset of moderate/severe PTOA.

Does total wrist denervation give reliable long-term results? Survival curve with an average follow-up of 8.2 years.

INTRODUCTION: Pain is the main reason why patients consult for degenerative and posttraumatic wrist conditions. While the many surgical techniques make choosing the appropriate procedure difficult, total wrist denervation, which has an "analgesic" aim, remains an accessible therapeutic solution to treat this symptomatology. Nevertheless, long-term results remain controversial, and few studies have focused on the survival of this procedure. HYPOTHESIS: Total wrist denervation provides lasting pain relief. PATIENTS AND METHODS: This was a single center, single operator (DLN), retrospective observational study. We analyzed 63 wrists. The mean age at the time of the procedure was 53.7 years. We verified the primary endpoint for survival, which included no further analgesic procedures and no significant residual pain (NRS≤3). Patient satisfaction and the quality of the wrist function were also assessed. RESULTS: The mean follow-up was 8.2 years. Some of the patients (12.7%) did not respond to treatment. We reported 1 neuroma of the superficial sensory branch of the radial nerve, 2 CRPS and 11 revision surgeries. We observed that the treatment became less effective over time. The median survival was 8.8 years. The survival rate of the procedure fell to 13.5% at the last follow-up. The mean residual pain was 3.4 on a numerical rating scale and the mean DASH score was 23.5. The mean satisfaction level, on a scale from 0 to 10, was 7.3 and most patients (79.6%) would undergo this procedure again. DISCUSSION: Survival of the total wrist denervation at the last follow-up was low in our study. Even though the treatment became less effective over time, the quality of the wrist function remained satisfactory and similar to the different studies previously published on the subject. There were very few complications and revisions. CONCLUSION: Total wrist denervation therefore remains an interesting surgical solution for patients with chronic wrist pain as it preserves mobility.
