Department of Orthopedic Surgery, Rouen University Hospital, Rouen, France.

Introduction: The innervation of the digital joints as well as the anatomical relationships of the articular branches is present in this anatomical work to determine the technical feasibility of a selective and efficient denervation of the digital joints.

Materials And Methods: A study of 40 distal interphalangeal (DIP), 40 proximal interphalangeal (PIP), 50 metacarpophalangeal (MCP), 10 interphalangeal (IP) of the thumb, and 10 trapezo-metacarpophalangeal (TMC) joints was performed on ten hands. Under magnification and a proper surgical approach, we collected the course, the source origin, the number of articular nerve branches, and their caliber.

Results: In total, 118 nerve branches arising from the proper palmar digital nerves were found on 10 DIP of each dissected long finger (n = 40). A total of 226 nerve branches were found on 10 PIPs of each long finger (n = 40), of which 204 branches (90.3%) had a palmar origin. Dorsal innervation was found for the ring and little finger, originating from the dorso-ulnar digital nerve. 212 branches were found on 10 MCP of long fingers (n = 40), including 87 branches of palmar origin (41.1%), 107 branches of dorsal origin (50.4%), and 18 branches of the motor branch of the ulnar nerve (8.5%). 42 articular branches directed to the TMC joint (n = 10) were found. 13 branches (31%) originated from the anterior sensory branch of the radial nerve, 13 branches (31%) originated from the lateral cutaneous nerve of the forearm, 5 branches (12%) originated from the palmar cutaneous branch of the median nerve, and 11 (26%) branches originated from the thenar branch of the median nerve. The involvement of the sensory anterior branch of the radial nerve was always present for the innervation of each TMC.

Discussion And Conclusion: Our research shows that finger joints receive their primary innervation from small branches of the digital nerves with the exception of the MCP joint and the TMC joint. To obtain an efficient and a selective digital denervation for articular pain relief, it is necessary to plan the best surgical approach and it is crucial to recognize the articular nervous branch localization and source.

Innovative adaptation of the "spare tissues concept" applied for olecranon coverage of a severe burn patient: A case report.

Ann Chir Plast Esthet 2021 Apr 7. Epub 2021 Apr 7.

Department of Maxillo-Facial Surgery, Purpan University Hospital, Toulouse, France.

Background: The management of bone exposure in patients with extensive burns could be a challenge due to the lack of healthy tissue. In such cases, it could be interesting to use any still healthy tissue initially destined for amputation and use it to cover up another site. We present the case of a sever burn patient for whom we used the only healthy palmar hand skin to cover an olecranon exposure.

Clinical Case Description: A 38-year-old man has been admitted in burn victim unit with extensive deep burns on 60% of the total body surface. An exposure of the left olecranon was appeared occurring on a burned area, with absence of healthy local tissues available for coverage. Concomitantly a trans-radial amputation was indicated because of severe digits burns leading to an impossibility to preserve the function of the hand. A palmar skin area was healthy leading to harvested this palmar skin flap pedicled on ulnar vessels. Early post-operative healing was satisfactory and no vascular suffering of the flap has been observed with a total healing at three weeks.

Conclusion: In any patient the spare tissues concept should be keep in mind when amputation is indicated simultaneously with a problematic of loss of substance coverage to a proximity area. In this case of severe burn patient, we used a palmar skin flap pedicled on the ulnar vessels to cover an olecranon exposure.

Perineal Wound Closure Following Abdominoperineal Resection and Pelvic Exenteration for Cancer: A Systematic Review and Meta-Analysis.

Cancers (Basel) 2021 Feb 10;13(4). Epub 2021 Feb 10.

Department of Plastic and Reconstructive Surgery, Toulouse University Hospital, 31100 Toulouse, France.

Background: Abdominoperineal resection (APR) and pelvic exenteration (PE) for the treatment of cancer require extensive pelvic resection with a high rate of postoperative complications. The objective of this work was to systematically review and meta-analyze the effects of vertical rectus abdominis myocutaneous flap (VRAMf) and mesh closure on perineal morbidity following APR and PE (mainly for anal and rectal cancers).

Methods: We searched PubMed, Cochrane, and EMBASE for eligible studies as of the year 2000. After data extraction, a meta-analysis was performed to compare perineal wound morbidity. The studies were distributed as follows: Group A comparing primary closure (PC) and VRAMf, Group B comparing PC and mesh closure, and Group C comparing PC and VRAMf in PE.

Results: Our systematic review yielded 18 eligible studies involving 2180 patients (1206 primary closures, 647 flap closures, 327 mesh closures). The meta-analysis of Groups A and B showed PC to be associated with an increase in the rate of total (Group A: OR 0.55, 95% CI 0.43-0.71; < 0.01/Group B: OR 0.54, CI 0.17-1.68; = 0.18) and major perineal wound complications (Group A: OR 0.49, 95% CI 0.35-0.68; < 0.001/Group B: OR 0.38, 95% CI 0.12-1.17; < 0.01). PC was associated with a decrease in total (OR 2.46, 95% CI 1.39-4.35; < 0.01) and major (OR 1.67, 95% CI 0.90-3.08; = 0.1) perineal complications in Group C.

Conclusion: Our results confirm the contribution of the VRAMf in reducing major complications in APR. Similarly, biological prostheses offer an interesting alternative in pelvic reconstruction. For PE, an adapted reconstruction must be proposed with specialized expertise.
