We studied the knees of 11 volunteers using RSA during a step-up exercise requiring extension while weight-bearing from 50° to 0°. The findings on weight-bearing flexion with and without external rotation of the tibia based on MRI were confirmed

A kindred of seven affected individuals in three generations is described with autosomal dominant inheritance of bilateral five-fingered hands, pedal polydactyly with syndactyly and agenesis of the tibia and of the lower end of the radius

1. A case of traumatic aneurysm of the anterior tibial artery complicating fracture of the tibia and fibula is reported. 2. The diagnosis and management of such lesions are discussed

Two cases of massive osteolysis of the lower extremities are reported. In one case a second lesion occurred in the opposite tibia and the process stopped after early total resection

Aims

Patellofemoral problems are a common complication of total knee arthroplasty. A high compressive force across the patellofemoral joint may affect patient-reported outcome. However, the relationship between patient-reported outcome and the intraoperative patellofemoral contact force has not been investigated. The purpose of this study was to determine whether or not a high intraoperative patellofemoral compressive force affects patient-reported outcome.

Objectives

Secondary fracture healing is strongly influenced by the stiffness of the bone-fixator system. Biomechanical tests are extensively used to investigate stiffness and strength of fixation devices. The stiffness values reported in the literature for locked plating, however, vary by three orders of magnitude. The aim of this study was to examine the influence that the method of restraint and load application has on the stiffness produced, the strain distribution within the bone, and the stresses in the implant for locking plate constructs.

1. Stress fractures are described in children. The fibula and tibia are most often affected. 2. Stress fractures of the humerus are described in two boys aged fifteen. 3. Stress fractures are described in the pelvis in children

As there is little information on the factors that influence fracture union following intramedullary nailing of the tibia we retrospectively investigated patient-, injury- and treatment-related factors in 161 patients with closed or grade I open fractures of the tibial diaphysis. The patients were reviewed until clinical and radiological evidence of union at a mean of 13.3 months (4 to 60). Multivariate statistical analysis using a Cox proportional hazards model showed that the risk of failure of union increased by 2.38 times for highly comminuted fractures, by 3.14 times when nail dynamisation was applied, and by 1.65 times when the locking screws failed. In fractures with no or only minimal comminution the risk of nonunion increased if the post-reduction gap was ≥ 3 mm

Aims

The aim of this study was to evaluate near-infrared spectroscopy (NIRS) as a continuous, non-invasive monitor for acute compartment syndrome (ACS).

A case is reported of fracture of the tibia in a haemophiliac, complicated by severe ischaemia. Extensive decompression of the limb followed later by skin grafting was required. The haematological management which made such surgery practicable is described. It involved the use of cryoprecipitate for a period of seven weeks

Objectives

To compare the effect of femoral bone tunnel configuration on tendon-bone healing in an anterior cruciate ligament (ACL) reconstruction animal model.

1. The case is reported of a girl born by normal delivery whose right lower limb showed reduplication of the femur below the single femoral head. 2. The tibia was absent but the ossific centres in the foot appeared to be normal. We are grateful to Processor Robert Roeaf for permission to publish details of this patient

1. A small mobile oxygen chamber is described which overcomes some of the disadvantages of using high pressure oxygen therapy in cases of general or local anoxia. 2. A case of limb ischaemia following an open fracture of the tibia and fibula is described in which such a method of treatment was used

We report our experience of lengthening by over 30% a total of 117 lower limbs in achondroplastic patients. We have compared four methods: transverse osteotomy, oblique osteotomy, callotasis of the shaft and chondrodiatasis of the epiphysis. Chrondrodiatasis of the femur and callotasis of the tibia are the techniques which gave fewest complications

Aims

The aim of this study was to estimate economic outcomes associated with deep surgical site infection (SSI) in patients with an open fracture of the lower limb.

Five elderly patients with chronic pyrophosphate arthropathy developed stress fractures of the tibia. All patients had deformed, painful knees with the result that their increasing symptoms were not readily attributed to a stress fracture. Such a possibility should be considered in patients with chronic pyrophosphate arthropathy since early recognition makes management of the stress fracture easier

Varus osteotomy of the distal femur is recommended for osteoarthritis of the knee with significant valgus deformity, but the operation is difficult to plan and perform. A simple technique involving a jig referenced to the line of the tibia is described. This allows accurate overcorrection by a few degrees, with impaction and secure fixation at the osteotomy. It has been successful, with no complications, in 12 consecutive knees

1. Exercise ischaemia in athletes with chronic pain over the postero-medial border of the tibia is described. 2. Fasciotomy of the compartment of the deep flexor muscles as a treatment of "shin splints" is recommended. 3. In eleven patients the symptoms were completely relieved and the athletes were able to start effective training within four weeks

Three cases of a rare complication of Salter Type II fracture-separations of the distal tibial epiphysis are described. Interposition of the anterior tibial neurovascular bundle between the displaced epiphysis and the lower tibia prevented reduction and, in two patients, the blood supply to the foot was compromised. Open reduction and internal fixation resulted in a satisfactory outcome in each case

A boy aged eleven with a solitary chondroma of the right tibia, and angiomata of the skeletal muscle, subcutaneous tissues, and periarticular tissues of the same limb, is considered to be a case of Maffucci's syndrome (dyschondroplasia with angiomata), although there was not the severe deformity encountered in the previously reported cases. There was a secondary atrophy and adiposity of skeletal muscle, and this was attributed to anoxic effects produced by the angiomata
