Closed nontraumatic flexor tendon ruptures are classified as spontaneous, infiltrative tenosynovial, iatrogenic, or attritional ruptures based on their mechanism. Attritional ruptures occur over rough bone surfaces that result from various pathologies. Here, we present a case of attritional rupture of the flexor digitorum profundus of the little finger due to pisotriquetral arthritis.

Background: A midshaft clavicle fracture is a common fracture that typically responds well to open reduction and internal fixation (ORIF). However, refracture can occur after implant removal (IR). This study aimed to analyze the rate of refracture and related factors after removal of the locking compression plate (LCP) for displaced midshaft clavicle fractures. Methods: We retrospectively reviewed the medical records of 201 patients who had undergone ORIF with LCP for midshaft clavicle fractures after IR after bony union from January 2011 to May 2018 at our institute. We evaluated basic demographic characteristics and radiographic parameters. All patients were treated with an LCP for primary fracture. The patients were divided into two groups: a refracture group that experienced a second fracture within 1 year after IR and a no-fracture group. Results: There were four cases (1.99%) of refracture; three were treated conservatively, while one was treated surgically. All patients achieved bony union. The average interval between refracture and IR was 64 days (range, 6–210 days). There was a significant difference in classification of fractures (AO Foundation/Orthopaedic Trauma Association [AO/OTA] classification) between the two groups. However, other patient demographics and radiographic measurements between refracture and IR, such as bone diameter, showed no significant difference between the two groups. Conclusions This study showed that one in 50 patients suffered from refracture after removal of the LCP. Thus, if patients desire IR, the surgeon should explain that there is a relatively higher possibility of refracture for cases with simple or segmental fractures than for other types of fracture.

Background: Locked posterior fracture-dislocation of the shoulder (LPFDS) is a very rare injury that occurs predominantly in young patients following high-energy trauma. The long-term outcome of the treatment of this injury is often poor. This study sought to present the characteristics of injury, discuss the pathological anatomy, and to report the treatment outcomes of our case series. Methods: Between January 2012 and May 2018, a total of 234 patients who underwent surgical treatment for proximal humerus fractures were reviewed. Among them, six patients (mean age, 54.7 years; range, 35–76 years) with LPFDS were included in this study. Four patients were treated with open reduction and internal fixation (ORIF) with locking plates, one with hemiarthroplasty, and one with reverse total shoulder arthroplasty. Clinical results were evaluated by Constant, American Shoulder and Elbow Surgeons (ASES), and visual analog scale (VAS) scores and radiologic evaluation was conducted using follow-up radiographs. Results: The mean length of follow-up was 26.2 months (range, 12–54). The mean Constant, ASES, and VAS scores were 66.7, 65.5, and 2.2, respectively. Four patients who underwent ORIF achieved bony union, but avascular necrosis (AVN) of the humeral head was observed in two patients. No complications were observed in the patients who underwent arthroplasty surgery until final follow-up. Conclusions In the treatment of LPFDS, replacement arthroplasty can produce predictable results. The approach of ORIF may be considered as a first choice of treatment in young patients but is sometimes correlated with postoperative complications such as AVN and the functional outcomes may be unpredictable. Therefore, patients should undergo careful diagnosis and treatment of this type of injury.

Transradial percutaneous coronary artery interventions are increasingly used because of low complication rates and patients' convenience. However, the radial artery is more vulnerable to damage due to its small diameter and frequent anatomical variations. We experienced a case of forearm compartment syndrome after transradial percutaneous coronary artery intervention which has not been reported in Korean literature yet. We report the case with a review of the literature.

During imaging studies or surgical procedures, anomalous forearm and wrist muscles are occasionally encountered. Among them, the flexor carpi radialis brevis is very rare. Because the trend is growing toward treating distal radius fractures with volar plating, the flexor carpi radialis brevis is worth knowing. Here, we report two cases with a review of the literature.

PURPOSE: Anteromedial surface of the leg is susceptible to trauma, which frequently induces soft tissue defect. When the size of a soft tissue defect is small to moderate, a local muscle flap is an easy and reliable alternative to a free flap. The authors performed medial hemisoleus flaps for reconstruction of soft tissue defects on the anteromedial surface of legs. The aim of this study was to evaluate clinical outcomes and effectiveness of the medial hemisoleus flap. MATERIALS AND METHODS: Twelve patients underwent the medial hemisoleus flap for reconstruction of a soft tissue defect on the anteromedial surface of the leg from February 2009 to December 2013. There were eight males and four females with a mean age of 47.8 years (15 to 69 years). The mean size of defects was 4.7x4.2 cm (2x2 to 9x6 cm). Flap survival and postoperative complications were evaluated. RESULTS: Mean follow-up period was 39.6 months (7 to 64 months) and all flaps survived. There were two cases of negligible necrosis of distal margin of the flap, which were healed after debridement. All patients were capable of full weight bearing ambulation at the last follow-up. CONCLUSION: The medial hemisoleus flap is a simple, reliable procedure for treatment of a small to moderate sized soft tissue defect on the anteromedial surface of the leg.

PURPOSE: Fractures of the distal humerus are one of the challenging injuries due to its complex anatomy and accompanied comminution. For dual plate fixation, orthogonal or parallel plating is widely used, but the better of the two is debatable. The purpose of this study was to report another fixation technique that yielded good clinical results with early bone union of distal humerus fracture, namely, posterior-posterior plate fixation. MATERIALS AND METHODS: From March 2003 to March 2012, 20 patients with distal humerus fractures were treated by posterior-posterior plate fixation. The triceps reflecting approach was used with anterior transposition of the ulnar nerve. The mean age at the time of injury was 45 years (range, 26 to 78 years). By AO classification of distal humerus fractures, there were one case of A2 and B3 respectively, two cases of each A3, C1 and C3, and twelve cases of C2. RESULTS: The mean period of complete bone union was 7.1 weeks (range, 4 to 11 weeks). The mean flexion-extension range of motion of the elbow joint at last follow-up was 116.2 degrees. The mean pronation was 81.2 degrees and supination was 83.1 degrees. Plates and screws were removed at about nine months after the initial surgery. No cases showed complications or required additional operation. CONCLUSION: Posterior-posterior dual plates fixation resulted in stable bicortical screw fixation, and insertion of lag screws were possible without interference. Posterior-posterior plating could be an easy and stable fixation method that provides good clinical results.
