Background It is unclear what the exact short-term outcomes of necrotizing soft tissue infections (NSTIs), also known and necrotizing fasciitis of the upper extremity, are and whether these are comparable to other anatomical regions. Therefore, the aim of this study is to assess factors associated with mortality within 30-days and amputation in patients with upper extremity NSTIs. Methods A retrospective study over a 20-year time period of all patients treated for NSTIs of the upper extremity was carried out. The primary outcomes were the 30-day mortality rate and the amputation rate in patients admitted to the hospital for upper extremity NSTIs. Results Within 20 years, 122 patients with NSTIs of the upper extremity were identified. Thirteen patients (11%) died and 17 patients (14%) underwent amputation. Independent risk factors for mortality were an American Society of Anesthesiologists (ASA) classification of 3 or higher (OR 9.26, 95% CI 1.64-52.31) and a base deficit of 3 meq/L or greater (OR 10.53, 95% CI 1.14-96.98). The independent risk factor for amputation was a NSTI of the nondominant arm (OR 3.78, 95% CI 1.07-13.35). Length of hospital stay was 15 (IQR 9-21) days. Conclusion Upper extremity NSTIs have a relatively low mortality rate, but a relatively high amputation rate compared to studies assessing NSTIs of all anatomical regions. ASA classification and base deficit at admission predict the prognosis of patients with upper extremity NSTIs, while a NSTI of the non-dominant side is a risk factor for limb loss.

Background: There are various treatments for post-traumatic distal radioulnar joint (DRUJ) dysfunction. The present study aimed to assess differences in long-term patient-reported outcomes on physical function, pain, and satisfaction between the Darrach and Sauvé-Kapandji procedures. Secondary aims were to describe the radiographic outcomes and to assess the difference in rate and type of complications and reoperations between these 2 procedures. Methods: We retrospectively analyzed 85 patients who had a post-traumatic DRUJ derangement and had been treated by either a Darrach (n = 57) or Sauvé-Kapandji procedure (n = 28). Fifty-two patients (61%) completed patient-rated outcomes surveys at a median of 8.4 years after their procedure. Radiographic measurements consisted of ulnar distance, radioulnar distance, and ulnar gap (only in Sauvé-Kapandji group). Results: There were no significant differences in Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) Function score, pain score, satisfaction score, complications, and reoperations between patients who had a Darrach procedure or a Sauvé-Kapandji procedure. Seventeen patients (30%) in the Darrach group experienced a complication, and 14 patients (50%) in the Sauvé-Kapandji group experienced a complication ( P = .09). The most common complication was instability of the ulnar stump (n = 10), followed by symptoms of the dorsal sensory branch of the ulnar nerve (n = 8). Patients who underwent a Sauvé-Kapandji procedure had more reoperations for excision of heterotopic ossification. Conclusions: Darrach and Sauvé-Kapandji procedures show comparable long-term patient-reported outcomes in treatment of post-traumatic DRUJ dysfunction. Complication and reoperation rate are relatively high, with non-significant differences between the 2 procedures.

Background: Neuromas are caused by irregular and disorganized regeneration following nerve injury. Many surgical techniques have been described to address neuroma with varying success. The aim of this study was to evaluate predictive factors for secondary surgery after initial surgical intervention for symptomatic neuroma along with a description of the anatomical distribution of surgically treated symptomatic neuromas. Methods: Five hundred ninety-eight patients with 641 neuromas that underwent primary surgery for neuroma were identified retrospectively. The diagnosis of neuroma was based on physical examination and patient history in the medical charts. Neuromas were treated by excision, implantation in muscle or bone, excision with direct neurorrhaphy with or without nerve grafting, or other treatments. Results: The rate of secondary surgery for neuroma was 7.8 percent, and secondary operations were performed at a median of 16.1 months. Excision alone or excision with implantation into bone or muscle had higher rates of secondary surgery compared with excision and direct neurorrhaphy with or without nerve graft. Neuromas were located in the upper extremity (49.61 percent), lower extremity (46.65 percent), and the groin/trunk (3.74 percent). Conclusions: Symptomatic neuromas are located predominantly in the extremities, and surgery can improve pain, with low secondary surgery rates. Excision with direct neurorrhaphy with or without nerve grafting was associated with lower reoperation rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.
