Ulnar nerve injury in closed fracture of forearm in children is uncommon.Commonly, neurapraxia is the reason for this palsy but other severe injuries or nerve entrapment has been reported in some cases. The importance of diagnosis concerning the types of the nerve injury lies in the fact that they have totally different management.We present a case of ulnar nerve deficit in a child following a closed fracture of the forearm bones. It is imperative to diagnose exact cause of palsy as it forms the basis for treatment. MRI scan can help diagnosis and accordingly guide the management. Simple nerve contusion should be treated conservatively, and exploration with fixation of the fracture should be done in lacerations and entrapments of the nerve. Surgery is not the treatment of choice in cases that could be managed conservatively.

Intramedullary interlocking nailing is the gold standard for treatment of tibial shaft fractures. The growing use of intramedullary nailing has resulted in an increased number of tibial nailing in daily clinical practice. Despite adequate surgeon experience, tibial nailing is not without complications if proper techniques are not followed. A case of iatrogenic talar neck and medial malleolus fractures during intramedullary nailing of tibia in a 24-year-old male is reported. It is believed to be caused by forceful hammering of insertion zig with foot dorsiflexed. To the best of our knowledge, no such case has been reported in the literature. It is possible to reduce the risk of this complication by adoption of preventive measures.

Simultaneous fracture/dislocation of the thumb carpometacarpal (CMC) joint and dislocation of the metacarpophalangeal (MCP) joint is considered as a rare injury pattern. We report an unusual case of dorsal dislocation of MCP joint of the thumb associated with extraarticular fracture of the base of the first metacarpal in a 28-year-old man. The dislocation of MCP joint had been missed during initial presentation at a peripheral centre. The patient made an uneventful recovery following open reduction and fixation with 1.25 mm Kirschner wire of the MCP joint along with repair of the ulnar collateral ligament. This injury pattern has not been previously reported to the best of our knowledge in the English-language based medical literature.

Guide wire plays an important role in the fixation of femoral neck fracture with dynamic hip screw (DHS). Breakage of a guide wire during operation is a very rare condition. We met such a dilemma in DHS fixation of a 54-year-old male patient who sustained Garden type IV fracture of the right femoral neck. The distal end of the guide wire broke and was entrapped in the fractured femoral neck. We tried to get the broken part out by a cannulated drill. Reaming was started with the cannulated drill slowly rotating around the guide K-wire until the reamer fully contained the target under fluoroscope. A bone curette was used to get the broken wire out but failed, so we had to use the cannuated drill to dredge this bone tunnel. Finally the broken wire end was taken out, mixed with blood and bone fragments. Through the existing drilling channel, DHS fixation was easily finished. The patient had an uneventful recovery without avascular necrosis of femoral head or non-union of the fracture at one year's follow-up. A few methods can be adopted to deal with the broken guide wire. The way used in our case is less invasive but technically challenging. When the guide wire is properly positioned, this method is very practical and useful.

Dynamic hip screw fixation is a commonly performed procedure for internal fixation of intertrochanteric femoral fractures. Arterial injury following the operative fixation is a rare but serious event. We present a patient who developed pseudoaneurysm of profunda femoris artery after internal fixation of intertrochanteric fracture with a dynamic hip screw. The diagnosis was confirmed by angiographic study and it was successfully treated by coil embolization.

With rapid advancement in surgical techniques and improvement in implant materials, rate of internal fixation for pubic symphyseal disruption in rotationally and vertically unstable pelvic ring injuries has increased. Among various modes of implant failure, screw/plate breakage and loosening are common complications following unstable fixation. Migration of loose screws into the urinary bladder has been reported as an extremely uncommon complication of pubic symphyseal plating. Here we present a case report of a 52-year-old female who presented with asymptomatic passage of screws in her urine following migration into the bladder, 2 years after symphyseal plating for pubic diastasis in an anteroposterior compression pelvic ring injury.

OBJECTIVETo study the role and effect of Schwann cells (SCs) remyelination in contused spinal cord.

METHODSGreen fluorescence protein expressing-SCs were transplanted into the epicenter, rostral and caudal tissues of the injury site at 1 week after the spinal cords were contused. At 6 weeks, the spinal cords were removed for cryosections, semithin sections and ultrathin sections, and then immunocytochemical staining of myelin basic protein (MBP), P0 protein (P0) and S100 protein (S100) was carried out on the cryosections. Qualitative and semiquantitative analyses were performed on the cryosections and semithin sections. Ultrastructure of myelinated fibers was observed on the ultrathin sections under electron microscope.

RESULTSTransplanted SCs and myelinated fibers immunocytochemically labeled by MBP, P0 as well as S100 distributed in whole injured area. The quantity of myelinated fibers labeled by the three myelin proteins showed no statistical difference, however, which was significantly larger than that of controls. On the semithin sections, the experimental group demonstrated more myelinated fibers in the injured area than the controls, but the fibers had smaller diameter and thinner myelin sheath under electron microscope.

CONCLUSIONSCs can promote regeneration of injured nerve fibers and enhance remyelination, which may be histological basis of SCs-mediated functional repair of injured spinal cords.

OBJECTIVEThe management of secondary normal pressure hydrocephalus (sNPH) is controversial. Many factors may affect the surgery effect. The purpose of this study was to identify the possible factors influencing prognosis and provide theoretical basis for clinical treatment of sNPH.

METHODSA retrospective study was carried out to investigate the results of 31 patients with sNPH who underwent ventriculoperitoneal shunt surgery from January 2007 to December 2011. We processed the potential influencing factors by univariate analysis and the result further by multivariate logistic regression analysis.

RESULTSFactors including age, disease duration and Glasgow coma scale (GCS) score before surgery significantly influenced the prognosis of sNPH (P less than 0.05). Further logistic regression analysis showed that all the three factors are independent influencing factors.

CONCLUSIONAge, disease duration and GCS score before surgery have positive predictive value in estimating favorable response to surgical treatment for sNPH.

OBJECTIVEManagement of Rockwood type 3 acromioclavicular disruptions is a matter of debate. Should we adopt conservative or operative measures at first presentation? It is not clear but most of the evidences are in favour of conservative management. We present our experience in managing these patients surgically.

METHODSWe present a prospective series of eight cases of chronic Rockwood type 3 acromioclavicular joint disruptions treated surgically. Anatomical reconstruction of the coracoclavicular ligament was done by artificial braided polyester ligament prosthesis.

RESULTSAll the patients were able to perform daily activities from an average of the 14th postoperative day. All patients felt an improvement in pain, with decrease in average visual analogue scale from preoperative 6.5 points (range 3-9 points) to 2.0 points (range 0-5 points), Constant score from 59% to 91% and American Shoulder and Elbow Surgeons shoulder score from 65 to 93 points postoperatively. These results improved or at least remained stationary on midterm follow-up, and no deterioration was recorded at an average follow-up of 46 months.

CONCLUSIONThis midterm outcome analysis of the artificial ligament prosthesis is the first such follow-up study with prosthesis. Our results are encouraging and justify the further use and evaluation of this relatively new and easily reproducible technique.

OBJECTIVETo report a case series of six neglected cervical spine dislocations without neurological deficit, which were managed operatively.

METHODSThe study was conducted from August 2010 to December 2011 and cases were selected from the out-patient department of Postgraduate Institute of Medical Education and Research, India. The patients were in the age group of 30 to 50 years. All patients were operated via both anterior and posterior approaches.

RESULTSDuring the immediate postoperative period, five (83.33%) patients had normal neurological status. One (16.67%) patient who had C5-C6 subluxation developed neurological deficit with sensory loss below C6 level and motor power of 2/5 in the lower limb and 3/5 in the upper limb below C6 level.

CONCLUSIONThere is no role of skull traction in neglected distractive flexion injuries to cervical spine delayed for more than 3 weeks. Posterior followed by anterior approach saves much time. If both approaches are to be done in the same sitting, there is no need for instrumentation posteriorly. But if staged procedure is planed, posterior stabilization is recommended, as there is a risk of deterioration in neurological status.
