Ninety-one nerve injuries (median; 36, ulnar; 43, radial; 12) involving the upper extremity in 66 patients were studied over a twelve-month period. The results for the median, ulnar and radial nerves after nerve repair were analyzed with respect to the suture method, the age, the level of injury and the time interval from injury. The results were obtained as follows: 1. Sympathetic nerve function returned from 6 weeks (average) after operation. 2. There are better results in perineurial suture than in epineurial suture. 3. There are better results in under 16 years old than over 16 years. 4. There are better results in high level injury than in low level. 5. There are the best results in the delayed primary suture, the next in the primary suture and the last in the secondary suture. 6. Good recovery in motor function was observed in radial, median and ulnar nerve in order.

In the evaluation of peripheral nerve injury, nerve conduction studies and needle electromyography mainly focus on anatomical localization and functional evaluation of lesions. Whereas neuromuscular ultrasound has an advantage in structural assessment of lesions. In addition, muscle ultrasound can also be used to demonstrate muscle denervation without causing pain. We report a case of traumatic ulnar nerve injury at hand in which muscle ultrasound contributed to precise localization by provided detailed information about the extent of muscle denervation.

Although the musculoskeletal injuries associated with break-dancing which is gaining more popularity among adolescent and young people has been reported, the report regarding a peripheral nerve injury associated with breakdance is scarce. We report a rare case of a young amateur break-dancer, 'b-boy' who suffered from a painful paresthesia in his left hand, later diagnosed as type III Guyon's canal syndrome. A 23-year-old, right handed college man presented with a tenderness over the left hypothenar eminence and painful paresthesia over the ring and little fingers of 3 months duration. He trained himself as an amateur 'b boy' break-dancer for the last 10 months. Conservative management under the diagnosis of wrist sprain before presentation did not improve his hand pain. An magnetic resonance imaging and electrodiagnostic study revealed that painful paresthesia was caused by type III Guyon's canal syndrome, and 4 weeks of corticosteroid treatment was given with resolution of pain and paresthesia.

OBJECTIVE: To determine the incidence of peripheral neuropathy occurring in post-acute spinal cord injury patients. METHOD: We retrospectively reviewed the distribution of involved nerves in 94 spinal cord injury patients (men: 77, mean age: 45.2 years) who underwent electrodiagnostic studies at an early stage of rehabilitative therapy between March 1999 and June 2007 and looked for the existence of peripheral neuropathy according to the injured area (cervical/ thoracolumbar cord). RESULTS: The incidence of peripheral neuropathy observed on electrodiagnostic studies was 38.3% (36/94). Twenty-one (46.7%) of 45 patients with injured cervical cords exhibited peripheral neuropathy, and 15 (30.6%) of 49 thoracolumbar cord injury patients exhibited peripheral neuropathy; hence, tetraplegia had a higher incidence. The most commonly involved nerve was the peroneal nerve (24 cases), followed by the median nerve (9 cases) and the ulnar nerve (9 cases). CONCLUSION: The incidence of peripheral neuropathy observed in electrodiagnostic studies was high in spinal cord injury patients at the initiation of intensive rehabilitative therapy. The incidence of peripheral neuropathy in cervical cord injury patients was higher than that seen in thoracolumbar injury patients. Active education and training concerning appropriate bed positioning are necessary for spinal cord injury patients at an early stage after injury to prevent peripheral neuropathy.

Total elbow arthroplasty was initially used to manage the rheumatoid arthritis of elbow. With the developement of technology in recent decades, the indication of total elbow arthroplasty include the trauma associated unstable joint, traumatic arthritis and distal humerus fractures in elderly. But the high risk of complications, which includes infection, ulnar nerve deficit and tricep insufficiency, is still an unsolved issue. The most widely used approach nowadays is the Bryan-Morrey approach, while some authors also report triceps on approach recently. This article is an overview in approaches and biomechanical researches of total elbow arthroplasy by reviewing the domestic and overseas involved literatures.

OBJECTIVE: To estimate the application of prognosis evaluation of ulnar nerve injury by 1H-magnetic resonance spectroscopy (1H-MRS). METHODS: The metabolites of first dorsal interossei (FDI) of two hands from 12 healthy volunteers and 1 volunteer with complete ulnar nerve injury were detected by 1H-MRS and the data were statistically analyzed. RESULTS: For the FDI of healthy adults, the female peaks area of extra-myocellular lipids (EMCL) was higher than the male (P < 0.05); There was no significant difference in Cho, Cr and intra-myocellular lipids (IMCL) between male and female (P > 0.05); There was no significant difference in all the peaks area between the left and right hand (P > 0.05). The EMCL peak of the injury side was higher than that of the healthy side, and the area of FDI was reduced in the volunteer with ulnar nerve injury. CONCLUSION Noninvasive and quantitative detection of 1H-MRS may be valuable for prognosis evaluation of peripheral nerve injury.

A 45 year old woman was diagnosed as having anteromedial radial head dislocation and distal radius fracture five months after her injury on right forearm. The radial head dislocation led to ulnar nerve compression. She had severe restriction of her elbow movements. She was treated with arthrolysis, decompression of the ulnar nerve and radial head resection. The reverse Essex Lopresti injury and radial head dislocation compressing the ulnar nerve has not been reported in English language literature to the best of our knowledge. A mechanism is proposed for the injury. In acute presentations, restoration of both the radioulnar joints should be done and neglected nature of such injury leads to suboptimal outcomes.

OBJECTIVE: To study injuries involving brachial plexus and its branches. METHODS: 66 cases collected from 2003 to 2005 in our department were analyzed statistically. RESULTS: 94% of injuries involved young adult males; 94% were blunt force injuries; 34% involved both nerve and bone mainly involving ulnar nerve and ulnar bone (50%); 40% of the injured nerves received electromyogram and 15 nerves were diagnosed with injuries clinically. CONCLUSION Forensic determination on severity of brachial plexus injuries mainly depends on movement recovery of limb. The best time for forensic appraisal is 20 d post operation+L (length of nerve severed distally)/R (growth rate)+90 d.

Ninety two injuries of the main nerves in the upper extremity observed in 79 patients, were studied at the Department of the Orthopedic Surgery, 17th Army Hospital from May 1965 to Aug. 1968. The treatment given consisted of neurolysis in 15, neurorrhapy in 77(primary 43 and secondary 34) and tendon transplantation and transfer in 11 cases. The results for the median, ulnar and radial nerves after primary and secondary suture were analyzed with respect to the level of injury(high and lower). The results of the median nerve repair were more succesful than those of the ulnar nerve, In these two nerve injuries, the sensory recovery was better than the motor and secondary suture gave better results than primary suture. Thirteen cases failed to respond to primary or secondary nerve repair, among those tendon transfer or tendon transplantation was tried in eleven cases, from the latter approximately 25% of motor recovery could be seen.
