The double compression syndrome of the ulnar nerve is a rare condition. Herin, we experienced double compression of ulnar nerve at cubital tunnel and Guyon's canal by re-evaluation after surgical decompression of cubital tunnel. We might suspect the double compression lesion in cases of worsening of symptom or nerve conduction velocity findings in a relative short duration of symptom as in our case. Meticulous physical examination might be needed to detect the Guyon's canal syndrome as a comorbidity in the treatment of cubital tunnel syndrome and re-evaluation for dual compression might be recommended if the resolution of symptom was not achieved after surgical decompression of single nerve lesion.

Indicators for local steroid injection on the hands include trigger finger, De Quervain's disease, carpal tunnel syndrome and trapeziometacarpal joint arthritis. Local steroid injection is an effective technique for rapid alleviation of symptoms and return to daily life. Complications following local steroid injection include depigmentation of the skin, subcutaneous fat atrophy, infection and tendon rupture. Tendon rupture and infection rarely occur as severe complications, and local steroid injection should not be abused or misused. The authors experienced a rupture of the extensor mechanism at extensor zone V after repeated local steroid injection to treat vague pain in the second metacarpophalangeal joint, followed by reconstruction of the extensor mechanism through tendon transfer and sagittal band reconstruction. We herein report a case with the literature review.

Synovial chondromatosis is a rare, benign and progressive metaplasia of the synovial membranes associated with the formation of cartilage in joints, tendon sheaths, or bursae. There are a few reports of synovial chondromatosis with wrist involvement. Here, we report a case of a 59-year-old woman with synovial chondromatosis of the ulnocarpal joint of the right wrist, with an 18-month follow-up and review of the literature.

Heterotopic ossification is one of the well known complications related to burn and mainly involves major joints and lower extremity, but heterotopic ossification of the hand has been rarely reported. The authors experienced treatment of heterotopic ossification in post-burn scar contracture of the wrist by wide excision with full thickness skin graft and there was no complication such as recurrence. As heterotopic ossification with ulceration is hard to cure with conservative treatment, it must be removed completely by surgical treatment. If ulceration in burn scar of the hand doesn't heal with the conservative treatment, differential diagnosis of heterotopic ossification will be made first.

PURPOSE: Electric saw is widely used and patients involved with the tool are increasing. We made efforts to analyze data of saw-related hand injuries. METHODS: Electric saw-related hand injuries that required operation were analyzed retrospectively by reviewing medical charts, clinical photographs and X-ray films from 2009 through 2013. Additionally, we interviewed patients regarding the type of electric saw involved (hand-held/table-mounted) and how the hand was injured. RESULTS: There were 16 male patients with 19 injured fingers and 22 injured tendons. Due to the damaging mechanism of the electric saw, injuries were severe and complex such as tendon, bone defects, fractures and amputations. 4 fingers had open fractures. Separately, 4 were amputated. Non-dominant hands were injured more by hand-held saw, while, dominant hands were damaged more by table-mounted saw. The thumb and index fingers were injured mostly by electric saw. Probability of dominant and non-dominant hand injury depends on the types of electric saw because of the working position when using this tool. CONCLUSION: Hand injuries can be classified according to the type of electronic saw used. Complete understanding of a specific trauma mechanism and the resulting injury patterns is important especially for hand surgeons. Surgeons should take into account the type of electric saw when examining patients. However, the most important step to prevent these types of injuries is to provide all workers with appropriate training and precautions before using the electric saw.

PURPOSE: We evaluated clinical outcomes after treating patients with proximal interphalangeal (PIP) joint fracture-dislocation with dynamic external fixator with which early joint motion can be undertaken to prevent joint stiffness effectively and fixate joints firmly. METHODS: Dynamic external fixators were applied for 20 fracture-dislocation of the PIP joints in 19 patients. The joints involved were 2nd PIP joint in two patients, 3rd PIP joint in three patients, 4th PIP joint in five patients, 5th PIP joint in eight patients. One patient had both 3rd and 4th PIP joint fracture-dislocation. Surgery was performed at least within four weeks. The mean age of the patients was 30.5 years (range, 15-54 years) and the mean follow-up duration was 1.85 years (range, 1-2.3 years) years. All patients were clinically and radiologically assessed on an outpatient basis after being discharged. RESULTS: At the final follow-up, the mean range of motion of PIP joints in flexion was 100.1° (flexion range, 88°-110°), the mean extension lag was 3.0° (extension range, 0°-10°), and the mean visual analogue scale score was 0.8. On anterior-posterior and lateral radiographs, congruity of the joint was satisfactory and 1 mm step off was present in three cases. CONCLUSION: We attained satisfactory clinical outcomes on the recovery of joint movement and joint congruity after treating PIP joint fracture-dislocation injury with dynamic external fixator.

PURPOSE: Distal radius fracture is one of the most common factures, but incidence of concomitant scaphoid fracture is rare. The rarity makes diagnosing the concomitant scaphoid fracture often delayed. Thus, in this study, the authors examined the frequency of concomitant scaphoid injury in distal radius fracture and the type of distal radius fracture that is more commonly associated with simultaneous scaphoid fracture. METHODS: We examined a total of 212 patients who had received treatment for the fracture in our institution. They were divided into two groups, isolated distal radius fracture group and distal radius fracture group with simultaneous scaphoid fracture, and their age, gender, body mass index and distal radius fracture type in accordance with AO classification were compared between the two groups. RESULTS: Concomitant scaphoid fractures were found in 12 (5%) patients, and among them 10 cases were associated with type C distal radius fracture. Statistical comparison between the group with isolated distal radius fracture and the group with both distal radius and scaphoid fractures was made, and only comparison of distal radius fracture types showed statistical significance. CONCLUSION: It is imperative to make timely and appropriate diagnosis of accompanying scaphoid fracture, since delay in making the diagnosis usually lead to many complications. We conclude that further diagnostic imaging such as computed tomography is necessary to make the correct diagnosis of concomitant scaphoid fracture, especially in type C distal radius fractures.

PURPOSE: We report surgical results and the relationship between hamate hook fracture and flexor tendon rupture occurred during excessive golf practice or rounding. METHODS: The 16 cases of patients with fracture of hamate hook or flexor tendon injury caused by golf swing were examined retrospectively. Hamate hook excision were underwent in fracture alone, flexor tendon reconstruction with tendon transfer of 3rd or 4th flexor digitorum sublimus (FDS) were done in the flexor tendon rupture. Postoperative results were evaluated by means of American Society for Surgery of the Hand (ASSH) to compare total range of motion and the grip strength. RESULTS: The fracture gap was not far apart completely in computed tomography (CT) of hamate fracture alone cases. If the flexor tendon rupture with the fracture, the gap in CT was far apart completely. After flexor tendon transfer surgery, two cases were excellent, five cases were good, two cases were fair in ASSH assessment. One case was re-rupture. Grip strength as compared with the normal side was observed for the mean grip strength of 82% recovery. CONCLUSION: The instability of the hamate hook fracture affected to flexor tendon rupture rather than location of the fracture. Hamate hook excision and tendon transfer with FDS can be a good treatment option.

PURPOSE: To assess the clinical difference between cubital tunnel syndrome with anconeus epitrochlearis (AE) and idiopathic cubital tunnel syndrome without known other causes. METHODS: This cross-sectional study included the 326 patients who were subjected to surgery because of cubital tunnel syndrome from 2008 to 2014. After exclusion of patients with other known causes of cubital tunnel syndrome, a total of 107 patients were divided into two groups; patients with and without AE. The clinical differences between two groups were analyzed retrospectively; age, sex, presence of intrinsic muscle atrophy, interval from symptom development to surgery, pinch power, the disabilities of the arm, shoulder and hand score and the nerve conduction velocity (NCV). RESULTS: Thirty four (10.4%) patients, being subjected to surgery had the AE. Among 107 patients who had no other known causes, 26 patients had AE. 19 out of 26 patients with AE was male. Average age of patients with AE was significantly younger. The interval from symptom development to surgery in AE patients was significantly shorter. Motor NCV of ulnar nerve at above elbow joint in comparison with that at below elbow joint in AE patient was more significantly decreased (14.3 m/sec vs. 8.3 m/sec). CONCLUSION: The AE in cubital tunnel syndrome is no more rare structure. In younger male patients with rapidly progressive worsening cubital tunnel symptoms, and if there is significant decrease of ulnar motor nerve velocity at above elbow in comparison with at below elbow, the AE should be considered as cause of ulnar neuropathy.

PURPOSE: To evaluate the questions of hand and wrist section of Korean orthopedic in-training examination (KOITE). METHODS: We analyzed questions of hand and wrist section of KOITE between 2010 and 2014. The weight of hand and wrist section was calculated and topics were thoroughly analyzed. The construct of questions were evaluated and taxonomic classifications were also performed. The frequency of presentations of physical examinations and radiologic evaluations in diagnosis and treatment related questions were analyzed. The coverage of available references which were recommended by Korean Orthopedic Association (KOA) were analyzed. RESULTS: Sixty one out of 500 questions (weight: 12.2%) were related with hand and wrist section. Disease (30/61, 48.2%) was more commonly asked than trauma, however most frequently asked topic with a broad classification was fractures and dislocations (19/61, 31.1%). The description only questions (46/61, 75.4%) were most commonly asked construct of question. According to taxonomic classification, taxonomy B (diagnosis; 27/61, 44.3%) was most frequently asked. The Campbell's operative orthopedics (54/61, 88.5%) and textbook of KOA (53/61, 86.9%) were representative references covering questions most widely. CONCLUSION: This analysis of hand and wrist section of KOITE could be used as the check-up tools for resident training programs of each training hospitals.
