Operative Findings

Acute ulnar instability of the metacarpophalangeal joint of the thumb is divided into two distinct groups, according to the history, clinical, radiological and operative findings. In the first group it is a soft tissue injury, as a result of an unresisted abduction force to the thumb. In the second group, following a resisted abduction force, there is avulsion of a bony fragment from the base of the proximal phalanx, which is the site of common insertion of both the ulnar collateral ligament and the adductor pollicis. This is confirmed by post-mortem studies.

AbstractDuring a taekwondo competition, a 20-year-old female competitor injured her left thumb. There was pain, swelling, and tenderness at the ulnar side of the metacarpophalangeal joint. Plain radiography demonstrated an avulsion fracture with a small-size fragment at the base of the proximal phalanx. A mini hook plate was used to repair the lesion. The patient was satisfied with the results and returned to her sports activities after 2 months.

Subjective Result

70 patients with total avulsion or rupture of the ulnar collateral ligament of the first metacarpophalangeal joint were treated surgically, using an absorbable self-reinforced poly-L-lactide mini-tack placed through the ligament and a channel in the base of the proximal phalanx. The device stabilized the joint immediately, and 69 ligaments remained stable at 6 months. The subjective result was good or satisfactory in 66 of the cases. One case needed further surgery for pain in the scar and another developed local infection 9 months post-operatively. On the basis of these findings, the new absorbable fixation method seems to be a suitable method for clinical use.

Joint Effusions

Chapter 121 discusses US of the elbow, which is an important imaging modality for the evaluation of elbow pain, providing soft tissue resolution superior to MRI. Soft tissue injury of the elbow is usually caused by repetitive motion and chronic overuse. The most common indications for elbow US examination are joint effusion, tendon and ligament pathology, olecranon bursitis, and ulnar nerve entrapment. The distal biceps tendon, triceps tendon, and common extensor and common flexor tendons are easily evaluated with US. Dynamic evaluation can determine between partial- and full-thickness radial and ulnar collateral ligament tears. US easily identifies joint effusions and olecranon bursitis. Furthermore, US can be used to guide interventions about the elbow.

Abstract Background Knee pain incidence is increasing among the community which has different multiple pathologies. Magnetic Resonance Imaging (MRI) is considered the gold standard imaging modality in diagnosing knee soft tissue injury. Ultrasound (US) is another modality which can be used in diagnosing soft tissue injury. Aim of the Work is to detect the reliability of US in diagnosing cases with knee pain as compared to MRI. Patients and Methods A prospective study was conducted on 20 patients with knee pain. They were referred from the Orthopedic and/or Rheumatology Department to Radiology department at Ain Shams University hospitals for MRI and US examination of the knee.The age group were from 19 to 59 years. Results In this study, 20 patients were examined with majority being males (75%). US was tested against MRI for different soft tissue pathologies.including knee effusion, meniscal pathology (tear, degeneration and extrusion), medial collateral ligament sprain, lateral collateral ligament sprain and Baker’s cyst. There was good agreement between US and MRI in most of these pathologies. US showed an overall sensitivity of 61.7% and specificity of 92.7% with accuracy of 86.9%. The overall PPV and NPV were 66.1% and 91.3% respectively. Conclusion Ultrasound can be considered a reliable screening imaging modality in cases of knee pain.

AbstractA right-hand-dominant 55-year-old male automotive mechanic presented 24 hours following a hydrofluoric acid burn to the volar left thumb. Despite the severity of soft tissue injury, the neurovascular bundles were intact. Although a free toe-pulp flap is often described to cover volar digit defects, the resultant 6- × 4-cm full-thickness injury of the thumb was too large to be adequately covered by a toe-pulp flap or other commonly used local flaps from the ipsilateral hand. The authors used a superficial circumflex iliac artery perforator (SCIP) flap to reconstruct the volar surface of the thumb from the tip to the metacarpophalangeal joint. They used an arterial anastomosis with the princeps pollicis artery so that the anastomosis was well outside the zone of injury. The patient recovered from the procedure without event and was discharged home on postoperative day 5. At his 2-week postoperative visit, protective sensation with diminished light touch was intact. The authors conclude that the SCIP flap is a technically challenging but versatile, thin flap with minimal donor site morbidity that can be used to resurface the volar aspect of the thumb. The SCIP flap is a valuable resource for the hand surgeon confronted with larger soft tissue defects of the hand.

Surgical Closure

We retrospectively reviewed the surgical treatment for 16 cases of traumatic soft tissue injury to the metacarpophalangeal joint (Boxer’s knuckle). A history of trauma was present in all cases and there was an associated extensor tendon dislocation in seven cases. Eight cases were initially treated conservatively, but their symptoms persisted. Intraoperative findings included rupture of the extensor hood or joint capsule in all cases. Surgical closure of the rupture of the joint capsule resulted in a successful outcome in all cases. We consider that conservative treatment of this injury may not be effective when the joint capsule of the metacarpophalangeal joint is ruptured. We recommend arthrography of the metacarpophalangeal joint to assist in the decision as to whether to proceed with surgical or conservative treatment.
