Randomized Controlled Trial Comparative StudyPosterior lumbar interbody fusion versus intertransverse fusion in the treatment of lumbar spondylolisthesis.
To compare 2 methods of fusion in the treatment of lumbar spondylolisthesis: posterior lumbar interbody fusion (PLIF) and intertransverse fusion (ITF). ⋯ Morbidity and complications are much higher following PLIF than ITF. ITF is recommended because of the simplicity of the procedure, lower complication rate, and good clinical and radiological results.

Case ReportsNicolau syndrome following intramuscular diclofenac administration: a case report.
Nicolau syndrome (livedoid dermatitis) is a rare adverse reaction of a still largely unidentified pathogenesis at the site of intramuscular drug injection. The typical presentation is pain around the injection site soon after injection, followed by erythema, livedoid patch, haemorrhagic patch, and finally necrosis of skin, subcutaneous fat, and muscle tissue. The phenomenon has been related to the administration of a variety of drugs, including non-steroidal anti-inflammatory drugs, corticosteroids, and penicillin. ⋯ The lesion required multiple debridements and a partial-thickness skin graft. Subcutaneous injection, rather than intramuscular injection, was found to be a determining factor in this case. Clinicians must be cautious in the use of proper injection procedures, including appropriate needle length, in order to minimise complications.

Case ReportsGreater arc injury of the wrist with fractured lunate bone: a case report.
Carpal dislocation and fracture dislocation are uncommon and difficult to treat. Early diagnosis and treatment of such injuries are necessary to prevent progressive carpal instability and traumatic arthritis. ⋯ We present a case of greater arc injury of the right wrist with fractures of the lunate and ulnar styloid without perilunate dislocation. This pattern of injury cannot be classified in the available literature on greater arc injury.

To evaluate treatment outcomes in primary malignant periacetabular bone tumour removal and limb salvage with or without bone-graft reconstruction. ⋯ Malignant periacetabular tumours are difficult to manage. Functional results of our patients with no reconstruction or with bone-graft bridging were fair. Patients undergoing internal hemipelvectomy may experience leg-length discrepancies, which can be balanced with shoe lifts.

ReviewSchwannomas of the hand and wrist: long-term results and review of the literature.
To review the long-term results of 14 cases of histopathologically confirmed schwannoma of the hand and wrist treated with intracapsular tumour removal. ⋯ Meticulous dissection with magnification can achieve complete tumour removal without neurological loss or recurrence. Intracapsular tumour removal provides good results with a low complication rate.
