Background: The purpose of this study was to review the outcomes associated with different surgical treatments in the management of suppurative flexor tenosynovitis (SFT). Methods: Patients treated by open drainage (OD) through a single incision and closed catheter irrigation (CCI) of the tendon sheath were evaluated from 2003 to 2009 at a single institution. Variables examined included culture results, time to surgery, duration of hospitalization and antibiotic therapy, pain, reoperation, and functional outcomes were recorded. Statistical analyses used included parametric and nonparametric t tests. Results: Twenty-four patients were treated for SFT with a mean follow-up of 3 ± 2 years. There were 13 (100%) males in the OD group compared to 8 (72%) males within the CCI group. Ninety-two percent of patients who underwent OD and 100% who underwent CCI reported none or mild pain. There were no differences between the 2 groups with regard to functional outcome scores. Factors leading to worse functional outcomes included prolonged time to receiving antibiotics and Staphylococcus aureus infection. Smokers required prolonged antibiotic treatment compared to nonsmokers. Accounting for planned returns to the operating room, there was no difference in reoperation rates between the OD or CCI groups. Conclusions: Surgical treatment of SFT with either OD or CCI resulted in similar outcomes for pain, function, and need for reoperation. Factors that lead to poor outcomes include S aureus culture, prolonged time to antibiotics, and smoking.

Abstract Tendon transfer options to reconstruct a massive irreparable posterior‐superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described the lower trapezius transfer using a 2‐incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic‐assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior‐superior rotator cuff tear.

Background: The purpose of this study is to describe a novel technique using an interposition vein graft for thumb replantation in these severe avulsion injuries. Methods: From 2002 to 2012, 8 patients underwent interposition venous bridge grafting from the dorsal radial artery at the anatomic snuffbox to the ulnar digital artery of the thumb. All patients had a traumatic thumb amputation with a severe injury to the ulnar digital artery. The technique began with bony stabilization; the radial artery at the anatomic snuffbox is exposed, vein graft harvested, and microsurgical end-to-side (proximally) and end-to-end (distally) anastomoses are carried out. Results: The average time to the operating room was 7.4 hours and time to reperfusion was 9.5 hours. At 3.1 years of follow-up, all 8 thumbs remained viable, without any need for revision procedures. The only complication was a metacarpal shaft nonunion treated successfully with iliac crest bone grafting. At last follow-up, all patients reported no or mild pain, with an average metacarpophalangeal (MCP) range of motion of 46.5°, and intact but diminished 2-point discrimination. All patients were able to return to work full-time. Conclusions: Due to the challenging nature of thumb avulsion injuries and the pronated position of the thumb, novel salvage alternatives are important. We describe a technique when no proximal vessels are available, using a vein to bridge the dorsal radial artery to the ulnar digital artery of the thumb. This novel arterial reconstruction has shown promise in thumb replantation associated with severe avulsion injuries.

Summary: Soft tissue wounds overlying the dorsum of the foot and ankle are difficult to treat, and historically have been treated with free tissue transfer. Advances in surgical technique have expanded the use of pedicle perforator flaps to avoid free tissue transfer in certain situations. The authors describe a technique for using an extensor digitorum brevis flap to provide soft tissue coverage for wounds of the ankle and foot. In the senior authors’ experience, the use of this flap has achieved wound coverage in 100% of patients with smaller wounds (≤45 cm2) of the ankle.

PurposeOur objective was to determine the prevalence and quality of restored external rotation (ER) in adult brachial plexus injury (BPI) patients who underwent spinal accessory nerve (SAN) to suprascapular nerve (SSN) transfer, and to identify patient and injury factors that may influence results.MethodsFifty‐one adult traumatic BPI patients who underwent SAN to SSN transfer between 2000 and 2013, all treated less than 1 year after injury with >1 year follow‐up. The primary outcome measured was shoulder ER. The outcomes we utilized included “clinically useful ER” (motion ≥ −35° with ≥MRC 2 strength), modified British Medical Research Council (MRC) grading, and electromyographic (EMG) reinnervation.ResultsEMG evidence of re‐innervation was found in 85% of patients. Surgery resulted in improved ER in 41% (21/51) of shoulders at an average of 28 months follow‐up. Of these, only 31% (17/51) had clinically useful ER. The average ER active range of motion was 12° from full internal rotation (Range: −60° to 90°) and MRC grade 2.2 (2–4). The only predictor of ER improvement was an isolated upper trunk (C5‐C6) injury. Improved ER was clinically evident in 76%, 37% and 26% of upper trunk (UT), C5‐C6‐C7 and panplexus injuries, respectively (P < 0.03).ConclusionsAlthough 85% had EMG signs of recovery, the SAN to SSN transfer failed to provide useful recovery of ER through reinnervation of the infraspinatus muscle in injuries involving more levels than a C5‐C6 root/upper trunk pattern. In patients with greater than C5‐6 level injuries alternatives to SAN to SSN transfer should be considered to restore shoulder ER. © 2016 Wiley Periodicals, Inc. Microsurgery 37:365–370, 2017.

Purpose In order to achieve an oncological margin during limb salvage surgery for tumours around the hip, part or the entire hip joint is frequently sacrificed. Hip arthroplasty restores a functional extremity and achieves limb salvage. Currently there is a paucity of data concerning the late complications, long-term survival, and the risks of re-revision following aseptic revision of a total hip arthroplasty (THA) performed following an oncological resection. Methods We identified 78 patients who underwent aseptic revision of a THA which was performed for an oncological process involving the hip from 1972 to 2006. All patients had a minimum 5 years of follow-up with a mean of 13 years. Outcomes were compared to 1,378 patients undergoing aseptic revision of a THA that was performed for a diagnosis of osteoarthritis. Results The mean 5-, 10-, 15-, and 20-year re-revision-free survival for an oncologic process of the hip was 100%, 85%, 69%, and 57%. Within this cohort, younger patients were at an increased risk of revision surgery. There was no difference in survivorship of the revision implant at any of the aforementioned time points between the oncologic and osteoarthritis cohorts. Patients with an oncologic diagnosis had a higher rate of dislocations, component wear, and loosening compared to the osteoarthritis group. Conclusion Late complications following revision surgery of THA performed for an oncologic resection are common. The results of this study provide information for counselling patients on implant survivorship and complications following aseptic revision THA after index surgery for an oncologic indication.

We conducted a review of 144 consecutive patients who underwent proximal row carpectomy from 1967 to 2010 for the diagnosis of wrist arthritis. At a mean follow-up of 13.4 years, patients experienced good pain relief with preservation (but not improvement) of wrist motion. A total of 17 patients (12%) required revision surgery at an average of 44.6 months. Improved pain, function, and survival outcomes were seen in those who underwent proximal row carpectomy after the age of 40, had a preoperative diagnosis of Kienbock’s disease, who underwent a concomitant neurectomy procedure, patients who were non-labourers, and patients who underwent surgery after 1990. Although 45% of patients developed moderate to severe radiocapitate arthrosis postoperatively, these findings did not correlate with clinical outcomes or risk of revision surgery. Patients with type II lunate and type II and III capitate shapes had higher rates of postoperative radiocapitate arthrosis. Level of Evidence: III, Prognostic

Purpose Carpal tunnel syndrome is a common entrapment neuropathy. When conservative management fails to relieve symptoms, carpal tunnel surgery is indicated. The surgical exposure for this procedure is commonly based on variable anatomic landmarks. The purpose of this study was to describe a fixed, easily referenced anatomical landmark for the distal extension of the transverse carpal ligament, the “Cup of Diogenes.” Materials and Methods Topographical landmarks including Kaplan cardinal line, palmaris tendon, and distal palmer crease were marked on six fresh frozen cadaveric wrist and hand specimens. The apex of the Cup of Diogenes is determined to be the confluence of the thenar and hypothenar musculature of the palm. Wrists were dissected and the distance between these landmarks and the superficial palmar arch, median nerve, transverse carpal ligament, and ulnar nerve were measured. Results In all specimens, the ulnar nerve was ulnar to this the apex of the Cup of Diogenes, while the median nerve was radial. The apex was proximal in all specimens to the superficial palmar arch. The apex marked the distal extent of the transverse carpal ligament in all specimens. Discussion Based on our results, we feel the apex of the Cup of Diogenes is a consistent, fixed anatomical marker for the distal extent of the transverse carpal ligament, marking a safe zone in the palm for surgical planning of incisions.
