A 57-year-old female presented with a history of a progressively enlarging palmar mass over three years, with associated numbness over the median nerve distribution and difficulty in gripping due to dimensions of the mass. Physical examination revealed a 4 x 5 cm, movable, non-tender mass over the thenar eminence and a 2 x 1 cm movable, non-tender mass over the center of the palm. Tinel’s sign was positive over the mass and the carpal tunnel.

Excision of the mass was performed under intravenous regional anesthesia. A curvilinear incision made from the thenar crease distally to the midline of the wrist overlying the carpal tunnel, proximally. Dissection was carried down to the transverse carpal ligament which was transected to allow visualization of the mass and its attachment to the median nerve.

The mass described in this present case report shares characteristics from cases in previously published literature. Its gross appearance was highly indicative of a lipoma and its close relationship with the median nerve suggested an epineural origin. Magnetic resonance imaging revealed a well-defined lesion, suggesting a mass that was more likely to be excised, potentially leading to better neurologic outcomes.

Intraneural lipomas (within the epineurium) are rare soft-tissue tumors that predominantly occur in the hand and forearm. Most cases reported involve the median nerve, followed by the radial nerve, posterior interosseus nerve and more rarely the brachial plexus. Compression of peripheral nerves by benign adipose tumors is infrequently reported in literature, with most publications restricted to case reports or series of a few patients. To the author’s knowledge, this is the first article describing an intraneural lipoma in the Filipino population.

OBJECTIVE: To evaluate the value of high-resolution ultrasound the diagnosis and prognosis of cubital tunnel syndrome. METHODS: From January 2018 to June 2019, 47 patients with cubital tunnel syndrome were treated with ulnar nerve release and anterior subcutaneous transposition. There were 41 males and 6 females, aged from 27 to 73 years old. There were 31 cases on the right, 15 cases on the left, and 1 case on both sides. The diameter of ulnar nerve was measured by high-resolution ultrasound pre-and post-operatively, and measured directly during the operation. The recovery status of the patients was evaluated by the trial standard of ulnar nerve function assessment, and the satisfaction of the patients was assessed. RESULTS: All the 47 cases were followed up for an average of 12 months and the incisions healed well. The diameter of ulnar nerve at the compression level was (0.16±0.04) cm pre-operatively, and the diameter of ulnar nerve was (0.23±0.04) cm post-operatively. The evaluation of ulnar nerve function:excellent in 16 cases, good in 18 cases and fair in 13 cases. Twelve months post-operatively, 28 patients were satisfied, 10 patients were general and 9 patients were dissatisfied. CONCLUSION The preoperative examination of ulnar nerve by high-resolution ultrasound is consistent with the intuitive measurement during operation, and the result of postoperative examination of ulnar nerve by high-resolution ultrasound is consistent with follow-up results. High-resolution ultrasound is an effective auxiliary method for the diagnosis and treatment of cubital tunnel syndrome.

Iliotibial band syndrome (ITBS), as an overused injury of the lower extremities, has developed into a common cause of lateral knee pain. At present, the treatment of ITBS includes drug therapy, muscle strength training, physical therapy, and surgical treatment. Among these methods, physical therapy, drug therapy, and surgical treatment can only alleviate the symptoms of patients. As a safe and effective treatment, lower limb muscle strength training can improve patients' muscle strength, correct abnormal gait, and reduce the recurrence rate of the disease by paying attention to the dynamic changes of patients' recovery process. At present, the pathogenesis of ITBS remains unclear, and the treatment methods are not unified. It is necessary to further study the biomechanical factors related to the lower extremities and develop more scientific and comprehensive muscle strength training methods.

OBJECTIVE: To investigate the efficacy of self-made arthroscopic single channel in the treatment of carpal tunnel syndrome. METHODS: Sixty patients with primary carpal tunnel syndrome treated from January 2014 to December 2019 were divided into arthroscopic group and traditional open operation group. There were 30 cases in arthroscopic group, including 12 males and 18 females, aged (47.5±4.5) years and the course of disease was (6.6±4.2) months. There were 30 cases in the traditional operation group, including 10 males and 20 females, aged (48.5±3.5) years, and the course of disease was (5.6±4.4) months. Both groups were unilateral. According to the anatomy of wrist joint and the characteristics of transverse carpal ligament and arthroscopy, the instruments including cannula, inner heart and hook knife were designed. The patients in two groups were treated with decompression of transverse carpal ligament using arthroscopy combined with self-made instruments and traditional open sergery. The incision length, operation time, intraoperative bleeding, hospitalization cost, hospitalization time and recovery time of the two groups were observed and compared. Boston Carpal Tunnel Questionnaire (BCTQ) score was used to evaluate the clinical efficacy of arthroscopy combined with self made instruments in the treatment of carpal tunnel syndrome. RESULTS: Compared with the traditional group, the arthroscopic group had significant advantages in incision length, operation time, intraoperative bleeding and hospital stay, but the total cost of hospitalization was increased. The Boston score was significantly higher in the arthroscopic group than that in the traditional group at 1 month after operation, but not at 3 and 6 months after operation. CONCLUSION Arthroscopy combined with self-made instruments in the treatment of carpal tunnel syndrome is more reliable, minimally invasive and simplified than open surgery, but the patients should be clearly diagnosed and appropriately selected before operation to achieve satisfactory clinical effect.

OBJECTIVE: To explore the safety of classic Acupotomy in the treatment of carpal tunnel syndrome. METHODS: Twenty six adult specimens (15 males and 11 females), aged 60 to 95(82.54±6.94) years old, were selected from 10% formalin antiseptic fixation. There were 52 sides(two of them could not be tested). The study period was from November 2017 to May 2018. The specimens were collected from the body donation center of the school of basic medicine, Peking University. The operation of releasing the transverse carpal ligament on the human body specimen was simulated by the classic acupotomy, and the distance from the four points to the surrounding anatomical structure was measured to calculate the direct injury rate to the nerve and blood vessels, and the shortest distance between the acupotomy and the nerve and blood vessels was defined as ≥2 mm as safety. RESULTS: In the experimental operation, the direct injury rate of nerve and blood vessel was 14% and 12% respectively. There was significant difference in the rate of direct nerve injury between the four injection points (<0.05). There was no significant difference in the rate of direct vascular injury between the four injection points (>0.05). Among the four points, there was a statistically significant difference in the safety of nerves(<0.05), and the safety of point 1 and point 3 of radial injection was higher than that of point 2 and point 4 of ulnar injection(<0.05). There was significant difference in the safety of blood vessels between the four points(<0.05), and the safety of radial point 1 was higher than that of ulnar point 2 and point 4 (<0.05). CONCLUSION The safety of the classic Acupotomy for carpal tunnel syndrome is related to the location of the needle entry point, and the safety of theradial proximal end of the needle is the highest.

OBJECTIVE: To explore the application and clinical effect of wide awake local anesthesia no tourniquet technique in the surgery of bilateral carpal tunnel syndrome. METHODS: From March 2016 to August 2018, 20 patients (40 sides) with bilateral carpal tunnel syndrome were treated by wide awake technique. All patients were female, aged from 32 to 56 (50.8±6.4) years old. The anesthetic, intraoperative and postoperative pain and anxiety were evaluated, operative field bleeding in operation were assessed, postoperative skin healing of surgical area and anesthetic complications were observed, and Kelly grading were used to evaluate recovery of function. RESULTS: Twenty patients were followed up from 6 to 9 months with an average of 7.8 months. There was light anxiety before injection (NRS score rangedfrom 1 to 3), slight pain occurred during injection on the first poke (NRS ranged from 2 to 3);no pain and anxiety during operation (NRS score was 0);mild or moderate pain (NRS score ranged from 1 to 6) without anxiety(NRS score was 0) after operation was occurred. Surgical skin healed well at the stageⅠwithout side effect of anesthetic. At final follow-up, according to Kelly grading, 30 sides got excellent results, 8 sides good and 2 sides fair. CONCLUSION Wide awake technique is safe and effective in treating neurolysis of bilateral carpal tunnel syndrome, and could receive good clinical effects.

Cubital tunnel syndrome (CuTS) is the second most common nerve compression neuropathy in the upper extremity. Intraneural ganglion cyst (IGC) within the ulnar nerve around the elbow, might present as CuTS. A 51-year-old Chinese man presented with paresthesia at the ulnar two digits of the left hand for one year. He was clinically diagnosed as severe CuTS. Nerve conduction study revealed marked axonal damage of the left ulnar nerve and ultrasonography showed a mass along the ulnar nerve, three centimetres proximal to the medial epicondyle, which was highly suggestive of Schwannoma. The mass was explored by a longitudinal incision. Intraoperatively, multiple cystic lesions were found within the epineurium of the ulnar nerve. Communication was seen between the elbow joint and the cyst. Swellings were partially excised under microscope. Decompression or partial excision of the cyst along with ligation of the articular branch should be the treatment of choice to prevent recurrence in case of IGC.

Distal humerus fractures require stable fixation and early joint motion, similar to other intra-articular fractures, but are difficult to treat adequately because of the anatomical complexity, severe comminution, and accompanying osteoporosis. In most cases, surgical treatment is performed using two supporting plates. Plate fixation can be divided into right angle plate fixation and parallel plate fixation. In addition, depending on the type of fracture, surgical procedures can be performed differently, and autologous bone grafting can be required in the case of severe bone loss. The elbow joint is vulnerable to stiffness, so it is important to start joint movement early after surgery. Postoperative complications, such as nonunion, ulnar nerve compression, and heterotopic ossification, can occur. Therefore, accurate and rigid fixation and meticulous manipulation of soft tissues are required during surgery.

Ganglion cyst is considered to be a usual cause of peripheral nerve compression. In this report, we present a rare case of ulnar nerve compression by a multi-septated ganglion cyst in the cubital tunnel. A 33-year-old left-handed male amateur tennis player developed progressive numbness and weakness in his right elbow, forearm, and hand for 1 year. Decrease of grip power was apparent in left hand. Clinical examination revealed a cystic mass at the posterior side of the elbow. Magnetic resonance imaging identified a ganglion cyst at the elbow. During surgery about 3 cm diameter epineural ganglion was observed compressing the ulnar nerve and was excised using microsurgery techniques. Three months postoperatively, the clinical recovery of the patient was very satisfactory and he restored his original performance in tennis match.
