We reviewed 13 patients with a complex fracture-dislocation of the proximal interphalangeal joint of a finger and one patient with a complex fracture-dislocation of the interphalangeal joint of thumb. We had treated these
We have tested the hypothesis that the meniscofemoral ligaments make a significant contribution to resisting anteroposterior and rotatory laxity of the posterior-cruciate-ligament-deficient knee. Eight cadaver human knees were tested for anteroposterior and rotatory laxity in a materials-testing machine. The posterior cruciate ligament (PCL) was then divided, followed by division of the meniscofemoral ligaments (MFLs). Laxity results were obtained for intact, PCL-deficient, and PCL-MFL-deficient knees. Division of the MFLs in the PCL-deficient knee increased posterior laxity between 15° and 90° of flexion. Force-displacement measurements showed that the MFLs contributed 28% to the total force resisting posterior drawer at 90° of flexion in the intact knee, and 70.1% in the PCL-deficient knee. There was no effect on rotatory laxity. This is the first study which shows a function for the MFLs as secondary restraints to posterior tibial translation. The integrity of these structures should be assessed during both imaging and arthroscopic studies of PCL-injured knees since this may affect the diagnosis and management of such
Open wedge high tibial osteotomy (OWHTO) for medial-compartment
osteoarthritis of the knee can be complicated by intra-operative
lateral hinge fracture (LHF). We aimed to establish the relationship
between hinge position and fracture types, and suggest an appropriate
hinge position to reduce the risk of this complication. Consecutive patients undergoing OWHTO were evaluated on coronal
multiplanar reconstruction CT images. Hinge positions were divided
into five zones in our new classification, by their relationship
to the proximal tibiofibular joint (PTFJ). Fractures were classified
into types I, II, and III according to the Takeuchi classification.Aims
Patients and Methods
The goal of this study is to investigate the relation between indicators of osteoporosis (i.e., bone mineral density (BMD), and Cortical Index (CI)) and the complexity of a fracture of the proximal humerus as a result of a low-energy trauma. A retrospective chart review of 168 patients (mean age 67.2 years, range 51 to 88.7) with a fracture of the proximal humerus between 2007 and 2011, whose BMD was assessed at the Fracture Liaison Service with Dual Energy X-ray Absorptiometry (DXA) measurements of the hip, femoral neck (FN) and/or lumbar spine (LS), and whose CI and complexity of fracture were assessed on plain anteroposterior radiographs of the proximal humerus.Objectives
Methods
The treatment of fractures of the neck of the radius in children is difficult, particularly if the angulation of the fracture exceeds 60°. Since 1994 we have used closed reduction and stabilisation with an intramedullary Kirschner wire in patients with grade-IV fractures according to the classification of Judet et al. In a retrospective analysis of a two-year period (1994 to 1996), 324 children with fractures of the elbow were treated in our department. Of these, 29 (9%) had a fracture of the neck of the radius; six were grade-IV
We reviewed 13 cases of osteochondritis dissecans of the patella followed-up for 18 months to 19 years. Two were treated conservatively with excellent results, and 11 by operation with six excellent, four good and one fair result. There was complete radiographic healing of the defect in 10 cases and partial healing in three. The size of the osteochondritic lesion appeared to be of prognostic significance. Osteochondritis dissecans of the patella is the result of repeated minor

This paper reports a prospective study of 72 consecutive patients with fractures or fracture-dislocations of the upper end of the humerus, treated during 1981. Most were elderly and treatment was conservative. Of the 72 patients 64 were followed up for a period of six months. Observations were made on the type of fracture, the speed and pattern of recovery of shoulder movements, on the time of commencement of physiotherapy, and on its duration. We found that with conservative treatment alone, 94% of our patients had good or satisfactory results at six months from
Splitting fractures of the humeral head are rare; part of the humeral head dislocates and the unfractured part remains attached to the shaft. We report eight cases in young patients. In five the diagnosis was made at presentation: three had minimal internal fixation using a superior subacromial approach, one had a closed reduction and one a primary prosthetic replacement. All five patients regained excellent function with no avascular necrosis at two years. In three the
The pattern of fracture-dislocation of the upper part of the sacrum is demonstrated in three patients. The fracture line followed the segmental form of the sacrum and was usually caused by a posterior force against the pelvis which had been locked by hip flexion and knee extension. Fractures of the lumbar transverse processes also occurred, presumably from avulsion by the quadratus lumborum muscle. The damage to the sacral plexus found in all three cases recovered after several months. Radiographs of the

Posterior dislocation of the shoulder is an unusual
In children with obstetric brachial plexus palsy (OBPP) who develop an internal rotation deformity of the shoulder, release of subscapularis improves the range of external rotation of the shoulder and the strength of supination of the forearm. We studied the strength of supination in 35 healthy adult volunteers at 45° of both internal and external rotation. The mean and maximum torques were greater in external than internal rotation by 8.7% and 7.5%, respectively. This was highly significant (p <
0.0001). The increased strength of supination in external rotation is probably because the maximum power of biceps, particularly the long head, may be exerted in this position. In children the difference may be even greater due to anatomical differences causing the dramatic increases in the strength of supination after surgery for OBPP. In adults our findings suggest that the supination exercises which are undertaken after
An experimental model was established to investigate the possibility of repairing cervical nerve roots damaged above the dorsal root ganglion, as occurs in traction
We reviewed 19 children who had undergone a new modification of the L'Episcopo procedure for obstetric brachial plexus palsy. Through an axillary approach the latissimus dorsi tendon was re-routed anteriorly to the humerus and then anastomosed to the teres major tendon routed posteriorly. At an average follow-up of four years two months, the mean increase in shoulder abduction was 26 degrees and the mean increase in external rotation was 29 degrees. No neurovascular
There is evidence to suggest that fractures heal more rapidly in patients with a head injury as a result of systemic factors released from the site of this
