Introduction: We performed a clinical and radiological study to determine the functional outcome in terms of union and shoulder function and other related complications associated with treatment of humeral diaphyseal fractures with Intramedullary nailing.

Methods and Patients: A review of 100 consecutive humeral nailing over a period of four years performed solely for diaphyseal fractures using Russell Taylor nails.

51 male and 49 female.

Average age of 48.0 (25.3–63.8IQR)

45 Simple, 46 comminuted and 9 pathological fractures.

70 were isolated and 10 were part of multiple trauma fractures.

91 closed and 9 open fractures.

52 fractures due to simple falls, 30 road traffic accident,9 pathological fracture,8 work related and 1 unknow cause.

Out of 100 nails, 90 were statically locked while 9 were locked proximally and 1 was locked only distally.

The outcomes were assessed clinically, radiologically and using the Disability of Arm Shoulder and Hand (DASH) function scoring system.

Statistically Cronbach’s alphas were calculated for the three scales of the DASH instrument. These scales were the function/symptom scale consisting of 30 items, sports/music module containing 4 items, and work module comprising 4 items.

Medians (interquartile ranges) and ranges are presented for numerical variables.

Mann-Whitney U tests (two-tailed) and Univariate and multivariate regression analysis were used.

Results: 90% fractures united initially and 4% had delayed union, giving cumulative union rate of 94%. Six non unions required a second procedure.

The DASH function scale scores was categorised into good 71 patients 85.5% (Score 0-< 25),

Medium 4 patients 4.8% (Score 25-< 40) and Poor 8 patients 9.6% (Score 40+).

Univariate and multivariate regression analysis showed, Increasing age (adjusted OR=0.96,95%CI 0.93–0.99,P< 0.01) and communited compared to simple fractures (adjusted OR=0.12,95%CI 0.03–0.45,P< 0.01) were associated with reduced likelihood of attaining full range of motion.

Male patients (unadjusted OR=2.37,95%CI 0.90–6.25,P=0.08) and patients involved in RTA compared to falls (unadjusted OR=4.5,95%CI 0.96–21.07,P=0.06) were associated with higher likelihood of attaining full range of motion.

85 % had no complication, while 15 % had complications.

One nerve palsy and one case of infection.

Seven patients required nail removal and 3 required removal of proximal locking screw.

Conclusion: To date, we have the largest series in the literature of antegrade nailing for diaphyseal fractures. In our series the vast majority of patients achieved desired functional outcome and union, hence we recommend the use of intramedullary nailing for humeral diaphyseal fractures. By eliminating surgical technique errors, complications can be reduced further and even higher union rates can be achieved.

Sciatic nerve palsy is a recognised complication of primary total hip replacement. In our unit this complication was rare with an incidence of < 0.2% in the past ten years. We describe six cases of sciatic nerve palsy occurring in 355 consecutive primary total hip replacements (incidence 1.69%). Each of these palsies was caused by post-operative haematoma in the region of the sciatic nerve.

Cases, which were recognised early and surgically-evacuated promptly, showed earlier and more complete recovery. Those patients for whom the diagnosis was delayed, and who were therefore managed expectantly, showed little or no recovery. Unexpected pain and significant swelling in the buttock, as well as signs of sciatic nerve irritation, suggest the presence of haematoma in the region of the sciatic nerve.

It is, therefore, of prime importance to be vigilant for the features of a sciatic nerve palsy in the early post-operative period as, when recognised and treated early, the injury to the sciatic nerve may be reversed.

Background: A common problem following total joint arthroplasty is urinary retention, which often necessitates catheterisation in the postoperative period. Most of these catheterisations are done as an emergency in the ward where the sterility is less than optimal.

Methods : A retrospective study of the incidence of emergency urinary catheterisation in 300 male patients who underwent total joint Arthroplasty under spinal anaesthesia over an eighteen-month period is presented. The patients were divided into three groups according to their age Group 1 (50 to 65 yrs), Group 2 (65 to 70 yrs) and Group 3 (70 + yrs).

Results: The incidence of catheterisation for acute urinary retention in Group 1 was 20%, Group 2 – 65% and Group 3 –69%.

Discussion: Urinary stasis predisposes to infection. The direct relationship between urinary catheterisation and infections in total joint Arthroplasty is already well documented. The potential for infection is compounded if the procedure is carried out in the unsterile ward environment. This study shows that the incidence of emergency catheterisation in patients aged 65 or above was high (average 67%) .

Conclusion: We conclude that these patients in groups 2 and 3 should be catheterised electively in the optimal sterile environment of the operating theatre. Catheterization should be performed after the patient has had the anaesthetic and the prophylactic intravenous antibiotic has been administered. The potential occurrence of joint and urinary tract infection is reduced and consequently patient morbidity is lessened.

Sciatic Nerve Palsy (SNP) is a recognised complication in Primary Total Hip Replacement after a transtrochanteric or a posterior approach (5). It is considered to be caused by direct trauma to the nerve during surgery. In our unit this complication was rare with an incidence of < 0.2% over the past ten years. However we know describe six cases of sciatic nerve palsy occurring in 355 consecutive primary THRs (incidence 1.60%) performed in our unit from June 2000 to June 2001. Each of these sciatic nerve palsies we believe was due to postoperative haematoma in the region of the sciatic nerve.

To our knowledge there are only five reported cases in the literature of sciatic nerve palsy secondary to postoperative haematoma (1). (Each of the six patients who developed SNP was receiving prophylactic anticoagulation).

Cases recognized early and drained promptly showed earlier and more complete recovery. Those in whom diagnosis was delayed and were therefore managed expectantly showed no or poor recovery. More than usual pain the buttock, significant swelling in the buttock region and sciatic nerve tenderness associated with signs of sciatic nerve irritation may suggest the presence of haematoma in the region of the sciatic nerve. It is therefore of prime importance to be vigilant for the signs and symptoms of sciatic nerve palsy in the early post operative period because if recognized and treated early the potential injury to the sciatic nerve may be reversible.

Supracondylar osteotomy for traumatic cubitus varus is usually considered to be difficult, and to have a significant incidence of complications. Most difficulty is in maintaining correction after operation. We report 20 osteotomies performed by a modification of French's technique and managed postoperatively with the elbow extended. When a plaster splint was used only three of seven cases had good or satisfactory results, two requiring revision. Postoperative management by straight arm traction maintained correction and achieved a good or satisfactory result in all 13 cases. This new technique is recommended.

Complete dislocation of the knee is a relatively rare condition. When it occurs as a result of high-velocity injury, such as in a road traffic accident, associated vascular injury is generally suspected. In low-velocity injuries, however, distal pulses are often maintained throughout, and the possibility of vascular injury may erroneously be discounted. We report four cases of low-velocity dislocation of the knee, only one of which had an overt vascular disruption, but three of which had arterial damage. On the basis of our experiences, we recommend arteriography in all cases of complete dislocation of the knee.

The detection and recording of vibration emission from human joints, a technique which we have termed "vibration arthrography", is a sensitive, non-invasive method for the objective study of the locomotor system. Using vibration sensors attached to bony prominences around the knee, we studied the joints of both normal and symptomatic subjects. Normal subjects produced three signal types--physiological patellofemoral crepitus, patellar clicks, and the lateral band signal. In symptomatic subjects we identified and categorised many signal types and related them to pathology. Lesions of the menisci produced distinctive signals, and it was possible not only to lateralise the tear, but in many cases to determine the type of meniscal injury present. Vibration arthrography promises to be a useful tool in the non-invasive diagnosis of knee disorders.

Ninety-eight children with severely displaced supracondylar fractures of the humerus were treated by straight lateral traction. After a mean follow-up period of 3.5 years there were 90 satisfactory and only eight unsatisfactory results. Cubitus varus was present in only four children, which compares favourably with the results of operative treatment. The indications for straight lateral traction, and the advantages of this method, are discussed.

A case of locked hypersupination of the distal radio-ulnar joint is described in which the ulnar displacement was purely rotational rather than volar. The mechanism of injury is discussed in the light of cadaveric dissections which reproduced the injury.

Serious neck injury in rugby football is becoming more common, especially in schoolboys. We report five who presented with spinal cord damage between 1977 and 1983, two in the 1982-83 season. The mechanisms of injury, the treatment, and the outcome are discussed. We suggest measures to reduce the incidence of this most serious injury and draw attention to the appropriate management in the critical phase directly after injury.
