Variable Adjustment Methods for Hemihamate Autograft Arthroplasty in Proximal Interphalangeal Joint Fracture/Dislocations: A Surgical Technique Revisited and Case Series.

ABSTRACT: Proximal interphalangeal joint fracture/dislocations, even after surgical correction, often lead to long-term complications including posttraumatic arthritis, prolonged joint stiffness, and chronic joint instability. A wide range of surgical techniques has been devised to resolve this issue, but none has been promising enough. Despite this circumstance, arthroplasty using a hemihamate autograft of size and contour that match the middle phalangeal base has progressed into one of more acceptable methods that provide both articular congruency and osseous stability. In this article, we introduce various types of proximal interphalangeal joint fracture/dislocations and individualized surgical approach using hemihamate autograft and lag screw and/or hook plate as fixation methods.

Chronic Intratendinous Tophaceous Gout in Repaired Second Extensor Digitorum Communis and Extensor Indicis Proprius Tendons: A Case Report.

ABSTRACT: A 26-year-old male patient visited outpatient clinic for pain and palpable mass at 2nd extensor digitorum communis zone V region since last year. He underwent a posttraumatic extensor tenorrhaphy on the same location 11 years ago. Otherwise previously healthy, his blood test revealed an elevated uric acid level. Preoperative magnetic resonance imaging scan suggested a lesion, such as tenosynovial hemangioma and neurogenic tumor. Excisional biopsy was performed, and total excision of the compromised second extensor digitorum communis and extensor indicis proprius tendons was also necessary. Palmaris longus tendon was grafted to the defect. Postoperative biopsy report confirmed a crystalloid material with giant cell associated granulomas, suggestive of gouty tophi.

Comparison of the Wide-Awake Approach and Conventional Approach in Extensor Indicis Proprius-to-Extensor Pollicis Longus Tendon Transfer for Chronic Extensor Pollicis Longus Rupture.

BACKGROUND: The wide-awake approach enables surgeons to perform optimal tensioning of a transferred tendon intraoperatively. The authors hypothesized that the extensor indicis proprius-to-extensor pollicis longus tendon transfer using the wide-awake approach would yield better results than conventional surgery. METHODS: A retrospective analysis was performed of the prospectively collected data of 29 consecutive patients who underwent extensor indicis proprius-to-extensor pollicis longus tendon transfer. Patients were treated with the wide-awake approach (group A, n = 11) and conventional surgery under general anesthesia (group B, n = 18). The groups were compared retrospectively for thumb interphalangeal and metacarpophalangeal joint motion, grip and pinch strength, specific extensor indicis proprius-to-extensor pollicis longus evaluation method (SEEM), and Disabilities of the Arm, Shoulder and Hand questionnaire score at 6 weeks and 2, 4, 6, and 12 months postoperatively. RESULTS: Group A showed significantly better interphalangeal joint flexion and total arc of motion at 6 weeks and 2, 4, and 6 months, and significantly better metacarpophalangeal joint flexion and total arc of motion at all time points. Interphalangeal and metacarpophalangeal joint extension showed no difference at all time points. Group A showed significantly better specific extensor indicis proprius-to-extensor pollicis longus evaluation method scores at 2 and 4 months, and Disabilities of the Arm, Shoulder and Hand questionnaire scores at 4, 6, and 12 months. Grip and pinch strength showed no difference at all time points. The complication rate and duration until return to work were not different between groups. CONCLUSION: Compared with the conventional approach, the wide-awake approach showed significantly better results in the thumb's range of motion and functional outcomes, especially in the early postoperative periods. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Extended thenar flap for two adjacent fingertip amputations.

The thenar flap is a well-described technique, but reports about its use in patients with multiple fingertip injuries are limited. This study aims to introduce a surgical technique of using an extended thenar flap for two adjacent fingertip amputations and to evaluate the clinical outcomes and related complications. From October 2013 to October 2016, 12 patients (24 fingers) underwent soft tissue reconstruction of two adjacent fingers with an extended thenar flap. At the last follow-up, the patients were assessed for cold intolerance in the reconstructed fingers; two-point discrimination (2PD); range of motion (ROM); functional outcomes using the quick disabilities of the arm, shoulder, and hand (DASH) score; functional and appearance outcomes using the Michigan Hand Outcome Questionnaire (MHQ); and time taken to return to work. The mean follow-up time was 13.5 (range: 12-16) months. All flaps survived. The mean total active ROM in flexion measured at the last follow-up was 255° (range: 245°-260°). Objective sensibility in the flaps was ascertained as an average static 2PD of 6.9 (range: 3-10) mm. The mean quick DASH score was 3.3 (range: 0-9.1). The mean MHQ score was 93.8 (range: 88-100). All patients returned to work within 6.2 weeks on average. There were no complications. The extended thenar flap technique is a good alternative for simultaneous coverage of small-to-large defects in two adjacent fingertips.
