We present the long-term results of open surgery
for internal shoulder rotational deformity in brachial plexus birth palsy
(BPBP). From 1997 to 2005, 207 patients (107 females, 100 males, mean
age 6.2 (0.6 to 34)) were operated on with subscapularis elongation
and/or latissimus dorsi to infraspinatus transfer. Incongruent shoulder
joints were relocated. The early results of these patients has been
reported previously. We analysed 118 (64 females, 54 males, mean
age 15.1 (7.6 to 34)) of the original patient cohort at a mean of
10.4 years (7.0 to 15.1) post-operatively. A third of patients with
relocated joints had undergone secondary internal rotational osteotomy
of the humerus. A mixed effects models approach was used to evaluate the effects
of surgery on shoulder rotation, abduction, and the Mallet score.
Independent factors were time (pre-and post-surgery), gender, age,
joint category (congruent, relocated, relocated plus osteotomy)
and whether or not a transfer had been performed. Data from a previously published
short-term evaluation were reworked in order to obtain pre-operative
values. The mean improvement in external rotation from pre-surgery to
the long-term follow-up was 66.5° (95% confidence interval (CI)
61.5 to 71.6). The internal rotation had decreased by a mean of
22.6° (95% CI -18.7 to -26.5). The mean improvement in the three-grade
aggregate Mallet score was 3.1 (95% CI 2.7 to 3.4), from 8.7 (95%
CI 8.4 to 9.0) to 11.8 (11.5 to 12.1). Our results show that open subscapularis elongation achieves
good long-term results for patients with BPBP and an internal rotation
contracture, providing lasting joint congruency and resolution of
the trumpet sign, but with a moderate mean loss of internal rotation. Cite this article:
1. Three cases of paralysis of the radial nerve after intensive muscular effort in extension of the elbow are described. Clinical and electrophysiological evidence is recorded. 2. There was motor and sensory affection of varying degree and extent in the distribution of the radial nerve. 3. The type of lesion in each case was that of neurapraxia, and rapid spontaneous recovery occurred in each case. 4. The level of the lesion was in the arm, below the origin of the branches to the triceps. 5. The cause of the lesion was thought to be compression by a fibrous arch related to the lateral head of the triceps. 6. The cases are discussed in relation to other instances of compression of nerves by fibrous arches, and an explanation is advanced for spontaneous recovery.
1 . A ten-year study of fifty-four operations for transplantation of the hamstring muscles in thirty-one spastic patients has been made. 2. Twenty-one patients were improved after operation, six were not improved, and in four the duration of follow-up was too short for proper assessment. One patient died from other causes. 3. Greatest benefit was not obtained until one year after operation. 4. The results varied considerably in different grades of spastic patient. Important factors affecting the results were age, sex, personality, balance and function of arm and hip. Hand and major hip operations should be carried out before hamstring transplantation. 5. The objectives of operation are discussed. These were most consistently achieved in older, more ambitious or more responsible males with good balance and with good arm and hip function. 6. Factors which were of less direct importance were mental capacity, minor degrees of limb length inequality, and foot deformities. 7. Operative correction of foot deformities should not be done before hamstring transplantation. 8. Serial plaster correction of the knee flexion deformity before operation is preferred to division of the patellar retinacula. 9. Transplantation of the hamstrings to the patella in spastics is under trial.
We describe a patient in whom an initially intact sciatic nerve became rapidly encased in heterotopic bone formed in the abductor compartment after reconstruction of the posterior wall of the acetabulum following fracture. Prompt excision and neural release followed by irradiation and administration of indometacin resulted in a full neurological recovery and no recurrence 27 months later.
We report a case in which compartment syndrome and tourniquet paralysis occurred simultaneously. This is a previously unreported combination which presents a diagnostic problem. We recommend that electrophysiological studies and continuous monitoring of compartment pressures should be used to minimise morbidity in high-risk cases.
We report the case of a 59-year-old man with severe knee pain and inability to flex his toes or invert his plantar flexed foot after an external rotation injury to his knee. MRI showed rupture of the popliteus with a haematoma compressing the neurovascular bundle in the proximal calf, and electromyography demonstrated signs of an axonotmesis of the posterior tibial nerve. There was progressive nerve recovery over 24 weeks. Isolated rupture of the popliteus should be considered in any patient with an acute haemarthrosis, lateral tenderness and a stable knee, especially after an external rotation injury.
We have reviewed seven patients who had triceps transfer after an old brachial plexus injury. All patients had a useful functional improvement with a good range of powerful elbow flexion; five patients could manage to bring their hand to their mouth. The basis of patient selection and the relative advantages of triceps transfer are discussed.
