Treatment and prevention of "hook nail" deformity with anatomic correlation.

The hook nail deformity is a relatively common complication after fingertip amputation. It can be corrected or prevented with a carefully performed surgical procedure. The nail plate is removed. The redundant nail bed that is folded over the tip of the terminal phalanx is carefully removed with an additional 2 mm that is supported by the terminal phalanx so that wound healing will not draw the nail bed over the tip of the phalanx again. The fingertip is then resurfaced by a V-Y advancement flap, with precautions taken to avoid all tension in the flap.

The false positive Lachman test.

Five patients with isolated rupture of the posterior cruciate injury following road traffic accidents were noted to demonstrate a "positive Lachman test". Stress radiographs while performing the Lachman manoeuvre confirmed that all 5 patients had only a posterior cruciate injury. Attention is drawn to the "false positive Lachman test" that indicates a posterior cruciate injury. The presence of a sag sign also establishes a diagnosis of posterior cruciate rupture and a positive Lachman test in this situation must be interpreted with caution.

Objective assessment of research performance.

Research output in academic institutions need critical and objective assessment. Publications are an important avenue by which research by an academic can be evaluated. Journals in which such publications appear may be ranked and weight age given to publications in highly ranked journals. The number of citations of an academic's work by peers is another assessment of quality of research output. Firstly subjective peer assessment although flawed by interpersonal bias has its merits especially when evaluation is by an outsider of the institution.

The dropped big toe.

Surgical procedures for exposure of the upper third of the fibula have been known to cause weakness of the long extensor of the big toe post-operatively. The authors present three representative cases of surgically induced dropped big toe. From cadaveric dissection, an anatomic basis was found for this phenomenon. The tibialis anterior and extensor digitorum longus muscles have their origin at the proximal end of the leg and receive their first motor innervation from a branch that arises from the common peroneal or deep peroneal nerve at about the level of the neck of the fibula. However, the extensor hallucis longus muscle originates in the middle one-third of the leg and the nerves innervating this muscle run a long course in close proximity to the fibula for up to ten centimeters from a level below the neck of the fibula before entering the muscle. Surgical intervention in the proximal one-third of the fibula just distal to the origin of the first motor branch to the tibialis anterior and extensor digitorum longus muscles carries a risk of injury to the nerves innervating the extensor hallucis longus.

Soft tissue "rheumatism" in sports.

Pain and stiffness of the injured region after prolonged periods of inactivity is commonly encountered following soft tissue injuries in sports. The injury in most of these instances is due to stress failure although occasionally an acute injury with a protracted course in recovery may develop similar symptoms. The most common of these condition are the enthesopathies, that include tendonitis and fasciitis, sprains and strains, bursitis, tenovaginitis and the fibrositis syndrome.

The Hitchcock procedure. A cause for failure: a case report.

A 40-year-old man with a tenodesis of the long head of the biceps brachii in the bicipital groove (Hitchcock's operation) for bicipital tendinitis had recurrence of pain seven months after the operation. Roentgenograms of the acromiohumeral interval, taken when the patient tensed the biceps brachii, showed significant upward migration of the humeral head with a decrease in the acromio-humeral interval on the operated side. The authors postulate that resection of the stabilizing, intraarticular segment of the long head of the biceps in the Hitchcock's procedure allowed the short head to draw the humeral head proximally, resulting in a decrease in the acromiohumeral interval and recurrence of impingement. This is one possible explanation for the poor long-term results of the Hitchcock procedure.

Surgical management of non-union of neglected fractures of the patella.

Three cases of non-union of the patella with large gaps between the fragments are presented. The patients' ability to cope with the problem was not entirely satisfactory. Surgical management by mobilization of the patellar fragments and fixation using the tension band principle achieved union of the fracture in all three cases. The patients also recovered an excellent, pain-free range of movement and strength in the affected knees.

Surgical management of arthritis.

The progression and manifestations of arthritis can to a large extent be controlled by medical measures. In the instance of inflammatory arthritis surgical synovectomy may have to be undertaken to control the disease. Once the arthritis has resulted in significant damage to the joints surgical intervention may be the only means of providing relief of pain and restoring function to the affected limb. Arthroplasty, arthrodesis, debridement and osteotomy remain the most used surgical procedures to achieve this.

Stress fractures around the knee in elderly patients. A cause of acute pain in the knee.

A review of the cases of sixteen elderly patients who had eighteen stress fractures around the knee revealed that thirteen fractures had been misdiagnosed, which led to inappropriate management of six. The most frequent factor contributing to misdiagnosis was the presence of other abnormalities of the knee for which the patient had previously consulted the physician. Conservative treatment with rest, walking aids, and, for some patients, splinting of the extremity resulted in relief of pain and healing of the fracture. A careful clinical assessment that includes new radiographs and, if necessary, bone scans is essential for early diagnosis in patients who have acute, incapacitating pain in the knee.

The role of the long head of biceps brachii in the stabilization of the head of the humerus.

The role of the tendon of the long head of the biceps in the stabilization of the head of the humerus was studied in 15 freely hanging anatomic specimen shoulders. Upward migration of the humeral head was measured by noting any reduction in the acromiohumeral distance in roentgenograms of the shoulder. There was a statistically significant decrease in the acromiohumeral interval on tensing the short head of biceps, but there was no significant change in the interval on tensing either the long head or both heads of the biceps brachii. Severing the tendon of the long head while both the heads were tensed caused a significant upward migration of the head of the humerus. One of the important functions of the long head of the biceps is to stabilize the humeral head in the glenoid during powerful elbow flexion and forearm supination by the main muscle. Sacrifice of the intraarticular segment of this tendon in surgical procedures of the shoulder may produce instability and dysfunction.

The arteriovenous pattern of the distal digital segment.

By injection of eosin dye with latex into 45 cadaveric fingers we were able to demonstrate: (1) a distinct digital pulp arch formed by the ulnar and radial digital arteries over the mid-point of the terminal phalanx in 93% of digits; (2) variations in size of the proper digital arteries to each digit; (3) numerous branches from the pulp arch to the tip of each digit and (4) a constant pattern of dorsal veins over the terminal segment in 89% of digits.
